...and I think I've succeeded! I have yet to beat my own game at the hardest difficulty (I came close...), but I thought I should share my chief inspiration so that people who are looking for a game like mine will be able to find, try out, and critique it. It's a game where a rat with big shoes to fill goes on his first space adventure to fight against the invading Meowster's army of fungi, cats, and robots.

By the way, how was everyone's process? This was challenging for me because I haven't made very many games before, and I struggle a lot with being timely. I know it may not look like it, but I spent almost my whole day every day for 10 days just working on this game! I lose focus and get tired easily, so I put on some anime in the background to help me keep on task. Also, later on in the jam, one of my friends offered to help me out with some graphics - she's the one who made the cover image and the awesome character portraits!
