First Prototype is out!
Finally, I got the “main” gameplay loop working! I still need a bunch of stuff in the game lifecycle (such as loading levels, menus, game over, etc), but the game is at a point where it is possible to at least test the input.
What game? I am making a QiX clone – I think that the QiX mechanic (you have to cut away the play area) is very closely tied with this theme.
Have a screenshot:

If you want to try it out, you can find the binaries (for desktop and android devices) here:
