Interesting! Could you expend on that? What would happen when you overlap an enemy? Do you lose all of the things that were used for that shape? What if you collected more blocks than you needed?
Viewing post in So I have this mechanic, what now?
The enemies would just like...disappear (screenshake, particle effects to accompany it obviously, maybe there's a points system?). I think the blocks around you would disappear too. If you collected too many it just wouldnt work, you have to be the exact same shape. So you kinda have to avoid these weird tetromino-like enemies while collecting squares in certain spots. I dunno how fun that would be tho, just an idea
