Really cool one button game that does what it needs to very well!
My one big complaint is the sound effects versus the background music are really startling, I had to mute the game to keep playing. Other than that, a refresh button built directly into the game would certainly have been a nice touch
There seems to be a lot you could add to this game to flesh it out further if you end up continuing it post-jam. Tons of options for more hazards, game modes, and perhaps having to control more falling blocks at the same time!
Fun entry, good job!
