Real solid design and imediately fun to pickup and play, I really enjoyed this one, the enemy variety made this quite engaging, and added some strategy to it with having to prioritize targets and plan escape routes to survive, The way you displayed the player's health is also pretty unique.
There's really quite a lot on display behind the minimalist aestetic, shame there's no sound or music (but hey for a jam that's understandable ^^) but with just that to add you got quite some game already !
Definitively Congrats ! :)
