I absolutely love the core mechanic of this game! I've only ever seen that kind of thing used in the context of "falling sand", but having it here and controlling the penguin was a great experience!
The "water boost" mechanic made me really excited about the possibilities of what else could be done in a game like this!
The "black screens" bug is definitely unfortunate, but it's an understandable issue when you don't have a ton of time to test and fix lol. Goodluck in the jam!
