I actually really liked the game! Played it for about 10 minutes. I was a bit frustrated about a few things.
1. The block seemed so inconsistent and there were times where I lost because I didn't get a block on the current tower.
2. If I shot the block, it would increase in size, but it was too big for me to jump on top of.
Overall I thought it was a great idea for the jam, but had some bugs that impacted major aspects of the game.
Good job!
