Interestingly enough before I settled on my theme, one of the ideas I had was to do a block puzzle in which you removed blocks from the play space. Thankfully I went in a totally different direction as your take on the idea was much better than mine haha! I couldn't think of any kind of interesting or unique mechanic when I was toying with the idea but your implementation is fantastic.
I love the idea that clearing the play space is the core objective, but in doing so each move becomes more difficult so you have to weight up a lot of factors each time. The music, sounds and art style all complemented it beautifully and it was very replayable. One of the best entries I've seen for the jam on all fronts. Great work :)
