I have just beaten the game in Iron Man Mode, I've died 7 times to the last boss (final phase) and the fifth boss (slime) took my soul. Great Game, keep developing.

Impressive. I haven’t managed to do that myself yet.

Tip for Boss 2: You can intentionally get down to 1 HP and destroy it before it can hit you, also if you kill it on the top part of the screen the "Red skeleton" always spawns on the bottom left corner, which is easier than the other spawn position (Top-Left)

Does not work for me just a black screen

It may be an unsupported browser, though it should work in most of them.

linux support when?

This is a real gem. I really appreciate the process notes in the description and comments section!

Great, difficult game! I love the retro ascetics! Superb work!

Si te gustan los plataformas, con estilo retro y con un sinfín de bosses a derrotar, sin duda, este SWEET HELL es para ti y en este GAMEPLAY te enseñamos por qué. Tu hermano ha usurpado tu trono, reuniendo una formidable defensa de monstruos legendarios. Ocho jefes te esperan en este juego, que es tan desafiante como el mismísimo infierno.

the game doesn't launch with the itch.io app

Hi, which engine did you use?

(+1)

I wrote my own 2D rendering classes in JavasSript ES6.

MAN this is very well put together! It holds all the limitations of the MSX and is superrrr inspiring! Congrats on the honorary mention! You nailed the style and the boss count!

This is one of the best modern retro games I've played. You should REALLY make a downloadable version of it. I would gladly pay for it.

The name is quite appropriate so far. It's frustrating but in a fun way! Any plans to make a downloadable version?

Really enjoyed this one ! Never played MSX game, but maybe I should check some of them out, if they are anywhere near this fun.

PS : I hope some madman will attempt the IRON MAN run.

This game is absolute fire! From the first boss you know how the tone is going to be, unfair, devious, creatures are between you and the throne and there is only one way to the top. 

Is incredible how much can be said with just sprites and gameplay! I felt that struggle and the final scene makes it all worth it. 

The battles mechanically are impressive I haven't had this much fun with a game in such a long time, it took me back to the classics, tight controls, excellent music and sound effects it all worked together to sell the experience. 

If there was more of this I would eat it up in an instant! It makes me imagine and that in itself is enough for me to give it high marks!

This game is frustrating as hell, but when you finally get to sit on the throne the amount of satisfaction you feel is amazing.

Hey, sweet. How do you even start coding a game like this in JS? I'm just a beginner.

Congrats on the finished game.

Hello!

I would recommend you first start with learning how to do Object-Oriented Programming in JavaScript. If you listen to other JS developers online, you will hear a lot about how Functional Programming is so much better than OOP. Those people usually do not make games and their opinion on OOP can be ignored. OOP is the best fit for games since most things in the world can naturally be represented as objects.

So you learn how do OOP using classes in ES6. Now you can represent things in your game as objects such as a Player, Enemy etc.. You can use inheritance if you need multiple objects to use the same foundation. For example, in my games every object inherits from an Entity class, which contains an update/draw/destroy function.

Use the ES6 module system since it's the modern way to handle multiple imports in JS today. I like to name my modules after their class names like this:

player.class.js:
export default class Player {
}
game.js:
import Player from './player.class.js';
const player = new Player();

This is my own personal opinion and many people do not agree with me, but I think it's okay to use fake encapsulation in JS as long as it is only done for code organization and you understand it doesn't actual protect the variables.

export default class Player {
    constructor() {
        this._x = 0; // _ implies private, so don't access this member outside the class
        this._y = 0;
    }
}

Then you decide on what type of rendering engine you want.

  • For 3D games, Three.js is the best choice.
  • For 2D games, you can either use Pixi.JS if you prefer a more graph based scene setup like in Unity.
  • Work directly with 2D canvas which gives you the most versatility.

    Here is a really simple example how to draw an image on a 2D canvas:
<html><body><canvas></canvas><image src="./test" />
<script>
const image = document.querySelector('image');
const canvas = document.querySelector("canvas");
const context = canvas.getContext("2d");
canvas.width = 500;
canvas.height = 500;
context.drawImage(image, 50, 50);
</script></body></html>

I prefer to load images using the Javascript fetch command rather than embedding them in the document.

You can create a "main loop" for your game using requestAnimationFrame:

let lastTime = 0;
const update = time => {
    const elapsedSeconds = Math.min(maxTimestep, (time - lastTime) / 1000);
    lastTime = time;
    // Update and draw your entire game here
    update();
    draw();
    requestAnimationFrame(update);
}

And that's pretty much it. The 2D canvas can be used to make both games like this with bitmap graphics or vector-based games using primitive line/shape drawing.

WOW Donitz! I am so grateful for this roadmap. I've just learned the basics of JS, ergo, I know about OOP and all up until adding things into the DOM.

But this is the exact pointer I was looking for. Thank you so much, again.

Where are the downloads? Can you make a free msx release?

(+1)

I can't add any additional uploads before the jam rating period is over, but after that I can upload the source.

can you code a full game run it and install it all by javascript on android or ios? like if you use an ide or js anywhere type app or next.js i have an iphone 12 and an Android 7.0 my iphone is on the latest 17.4 developer beta 2 OS and My Android Is Running Nougat 7.0 any help is much appreciated 

You sorta can. You can use WebView to embed a web browser in an app, or something like Cordova/PhoneGap/Tauri. The iOS web browser has been nerfed on purpose so that it can't really compete with apps, at least in the past. I don't know what the current state is.

Though it isn't quite optimal. If you want to make a game for Android/iOS/PC/Linux it's easier to get started with Godot (or Unity).

Tough as nails is right, and victory is all the sweeter for it.

Very nice, tight gameplay, nice challenges. Getting annoyed by the slime boss currently, the rest was quite ok'ish so far.

Edit: Ok made it through all of them. For me, the slime was most tricky :)

Yeah the slime is the most ridiculous of the bosses, and my personal favorite. I hope memorizing its attack pattern was fun!

At first a bit frustrating, but it was fun to find out the pattern indeed, made it a lot easier :-)

Super kick butt game! Tight controls and great old school challenge. A little hard for my older reflexes but still very well made! Great job!

Why is this marked as Adult?

Because for some reason the adult tag found its way into the tag list. I think it was meant to be action.
