This felt really good to play. It wasn't very clear what the enemy spawn portals were until I saw enemies coming out of them. I first thought they were puddles or something, I think that could be made clearer, but the on-screen instructions were very helpful!
I loved the animations, colours, sound effects and screenshake! Everything worked together nicely in a way that made sense.
What didn't make sense was the UI buttons. I got stuck on the game over screen for 30 mins lol.
