Pretty nice submission! The Graphics and gameplay were really good! Character progression(!!) one very cool point of the game! While the upgrades weren't exactly the ones I was hoping for-- to think "Wow! I really needed this!", still give quite some life to the game. Still, good job on keeping the game balanced. It's hard to not go overboard and add like some super OP upgrades.
The "Guide" character was a smart addition too.! In fact I'm really surprised how alive the game felt even without any living enemies and sounds! I learned a lot from your game that I'll take in account for my next jams :)
