A fun tunnel syndrome inducing shooter ^^. A bit more on the difficult side, but I liked that. I liked the bearded guy and the bosses. It feels a bit under-play-tested - if the metal boss decides to charge through you, there's no way to escape, he's too fast and big, and the player is too slow.
Pixels look all jaggy, and they change in size when moving. Well, that's a Unity issue, In my project (please rate it ;) - https://itch.io/jam/blackthornprod-game-jam-1/rate/319208) I spent a whole day trying to make the pixelart look smooth. Still wouldn't work until I turned rigidbodies off on most objects.
