@t0neg0d , I am using a framework I wrote for my game development.
I call it Galago…
I am still in the process of making this library open to the public as a plugin lib for people to use.
This library just helps with the workflow of one’s game and recently I added a 2D framework dyn4j to it.
Galago contains a sprite engine which is very BASIC but works for me.
Here is some links of my previous games and tests made with it:
Ludum Dare 32
Pixel Pong game
MiniLudumDare 58
Regarding this game, it is planned for android and PC. Currently only PC.
I am also doing it as a Mini Ludum Dare 59 entry.
