This game is really cute, I like the amount of enemy variations and the upgrades look pretty well balanced except for a single one
The hour hand damage upgrade feels like it doesn't do anything most of the time as the clock doesn't spin fast enough for it to be worth it. Maybe if there was instead a second hand whose damage you could upgrade instead of the minute hand doing the damage, it would feel more impactful like the other abilities
Seeing a PICO-8 game this jam was very cool, the idea is also executed pretty well! Not much to say really, well done!
