It seems like a fun concept! I wish that there was more level progression because I just dumped money into the upgrades early and then it kinda felt like a grind without difficulty progression for the next 4-5 levels. I also found that the slime random movement felt cool at first (and looks neat) but was mostly annoying since they would move on top of me and I didn't feel like I had much need for control of my movements once I ran out of swords (which weren't really needed).
I love the core concept/theme of the game as a fun take on Moonlighter and I think it could be explored way more. Well done for 7 days!
