I like the idea! I'm a huge sucker for idle games - having one where the end goal isn't infinite growth, but survival was interesting. The way to start the game was a bit unorthodox (had me scratching my head which key was "\" in that case, as I have a non-English keyboard layout). The powerups as they are, are also a bit unbalanced, but as you said yourself - it's not finished and that is something that can easily happen with a time limit like this.
I am glad you had fun making it! Enjoy your own journey developing games, and here is hoping you are allowed to drink water and your depression doesn't fill up too fast ;)
