heaps VS openfl

Maybe the engine used for Dead Cells, https://heaps.io ?

I've personally had a very good experience with Haxe and Haxeflixel (https://haxeflixel.com/) although Heaps (https://heaps.io/) seems to be more popular nowadays.

Haxe is very nice as a language, can easily cross-compile to a lot of targets, Haxeflixel is heavily inspired by some Actionscript framework and has a lot of goodies. Maybe Heaps is more mature, up to date and allows for more advanced features.

Not really the worst, but you can say my least favorite, and that would be heaps.io

Yeah I think it's ideal for 2D development. Look into heaps.io . . you might like it! These days it seems the best source of community for haxe is in their official discord server.

Many frameworks will let you export for the web, even if you don't code your game in JS. Unity, Godot, Bevy(?), heaps.io ... the list goes on and on.

It takes a little while to get comfortable with heaps.io, largely because tutorials in the Haxe world are pretty limited. Here's a good place to start:

I'm going to go out on a limb and say that most people use Unity or Godot for jams these days. But as long as your framework exports for the web, you should be fine. Personally, I use haxe and heaps.io, but it's a bit of an outlier and probably requires learning a new language on top of learning a framework.

Which is not an emulator, but more of a spiritual successor, following the same API, and with tools to convert Actionscript projects

The game was written in Haxe (the language) and OpenFL (the engine).

Ever looked at OpenFL?

https://www.openfl.org/

Couple notable games haves used it. Haxe is a pretty mature ecosystem as well, from what I’ve heard.

I spent my thirties working and unwinding with flash games with my kids, brings back nostalgia thinking about those nights.

I'm interested in updating Bosca Ceoil! But I can't really promise anything - it depends on an old actionscript music library called SiON , which makes this very difficult. Because the tool is open source, I've been looking into porting this library to haxe, which is slowly making progress: https://github.com/openfl/openfl/pull/2515

You should consider https://www.openfl.org/ instead. OpenFl provides all the flash apis and has been battle tested. Your flash product can be ported to use Haxe + OpenFL without much effort and can then be used as a desktop app or HTML5/JS based game.

Dicey Dungeons is created with Haxe, using my own framework, which is an extension on top of OpenFL and HaxeStarling

Heaps has it's own API, but other Haxe frameworks[1][2] reimplement the flash API. Some tools[3][4] help to convert AS3 source code to Haxe, and the typing and compiler are helpful to fix identify issues, so depending on the size and dependencies, conversion can be easy once you get past the main language differences.
