Very fun game, finished it. Would be very interested to see how much this game could evolve with a bunch of upgrades. My only two criticisms would be the whistle sound effect (had to lower the volume of it because it kept jumpscaring me lol), and the lack of a "Clear instructions" button. I kept finding myself manually taking the arrows off of the blocks, which took longer than I would like. Aside from that, really cool game. Congrats!!
