Hi! I’ve been working on Alchimix for a while now, mostly as a side project and more recently as a side project I spent way too much time on :sweat_smile:

The game was made with the following awesome tools:

Glad to see you’re finally releasing this!

I’m really liking the graphics. Who made these?

Thanks!

Graphics are a mix of:

  • Stuff I made myself with Aseprite (UI, most elements/objects)
  • Free or paid assets from itch.io (like the tiles used for the map)
  • And a more recent addition I’m not too proud of but which added a lot for immersion: the backgrounds are from chatgpt

Nice game vibe, congrats!

Hashlink for desktop (and mobile, though not released atm) build

Interesting, is this target fits one-for-all relative gamedev? I was under impression native builds should be better

I published an update to the free web demo, adding the world map and access to the 71 levels (instead of 4 previously) of Briswen Island.

Wow, what a gorgeous looking game - congrats! I’ve spent the last week trying to decide between Heaps and OpenFL for a game and I’m planning (after months of experimenting with ~15 other game engines) - can I ask what motivated you to choose Heaps over HaxeFlixel or raw OpenFL as the underlying engine for Alchimix? My impression is that Heaps is an especially strong contender when it comes to 3d, but for 2d only, my impression has been that the mobile friction is much lower with OpenFL/HaxeFlixel.

You said you’ve experimented with about 15 other game engines ! Whould you share which ones did you try, and what did you think of them?

Oooh, I would love to but it’s a mouth-full for sure! To avoid derailing this topic, in 1-3 days I’ll open a topic under the forums “Other” section and post an abridged bullet-point list of the engines, pros/cons, likes/dislikes, and dealbreakers I encountered for each (I’d actually have much more to say, but I’ll have to leave that for a rainy day blog post/novella) and why I’m now circling either OpenFL or Heaps. Would really like to hear if any experiences match or disagree with mine! To manage expectations, my explorations were very run-and-gun and I bounced off an engine the second I encountered just one or two dealbreakers.

I should probably write something “proper” about that choice at some point; in short I really prefer the way Heaps works and lets you do your thing vs flixel etc. trying to do everything [their own way].

Had fun with server side hashlink with this update :sweat_smile:

API is made with weblink and both API, database and workers replaying players’ games on server side are deployed using docker (mostly because getting hashlink to work on my server was a pita xD).
