It took me waaay longer than planned.

And I got myself into a couple of "infinite loops" (which ended up the level generation requiring to iterate among like 150000 items and do some math on them...) but I now officially have a playable prototype with the core mechanic! Yay!

There are still some stitches to be made to functionality - like main menu, and restart button... but the core functionality and level flow are now there!
