Thanks for playing the game!
There were a lot of last minute issues so unfortunately we weren't able to fix everything.
I was aware of the ammo issue but the upgrades should work. They just don't take your money properly and there isn't a visual indication you bought an upgrade. The multi-shot upgrade is a little wonky though.
I actually really wanted to add particle effects to the flowers. I only realized after play testing at the very end how hard it was to spot the bad flowers.
Appreciate the feedback.
