Hey Dezue, nice to see you here :)
I've added your requests (2 of 3) to the online doc.
Here some more details:
- Sprite sizes. As we were discussing on Bluesky, implementing bigger sprites isn't an issue at all. The max size of 64x64 was set because I was giving for granted that people would make smaller, graphically simpler games with a single atlas texture. Giving users the chance to use multiple maps and bigger sprites shouldn't be an issue, so it should be added without big issues.
- Export for web. This is a big one and something I was already asked for, if everything goes to plan I should be able to test if it can be done starting from next week. I don't like to make promises that I'm not 100% sure I can deliver, but I think it shouldn't be problematic to ship for the web.
- Support for spine animations. This can't be done in any way. The animations work with classic spritesheets, and I don't see any reason to bore you with minute details, but just know that implementing any other type of animation is literally impossible and would ask for a complete re-design, re-write of the engine that would change it to something very different and too generalist.
Hope this post was useful! Let me know if you have any question. :)
