Good premise, I had fun with my friend. Here are some notes on my side:
- It didn't need to be split screen as levels are fairly simple and small maybe you could've used group composer so 2 players are visible at all times
- Both player and role switching colors are red, it gives wrong idea
- Some levels end too quick(before you could read the level description)
- Projectiles could've pushed the opponent so you prevent them doing something
Overall, we had enjoyed your game, good job!
