Fun game. 2 things I would change:
- Automatically award the player the leftover friends at the end of a round. It would feel good since you already have to keep them alive anyways so the challenge is still there. (this is one of those things where nobody would complain if it was there but there are people like me who will complain that it's not.)
- A rapid fire bullet type would feel incredible. For me, the upgrades were a little underwhelming. They sounded incredible, but gameplay wise they felt a tad underpowered considering you hardly get them and they're limited to that short round.
Other than that, amazing. Had a ton of fun. 4/5
