Great game, felt like a mix of Nuclear Throne and Serious Sam, which obviously is fun as hell.
I like the visuals, the spritework is very nice and so is the enemy design. Sound design feels on point specially when it comes to killing stuff, since the weapon firing sound + the splash sound of an enemy dying makes it feel meaty and satisfying. Music is great too.
Only minor complaint is that sometimes at the end of the level items would get stuck on walls trying to get closer to the door, but it wasn't really a problem. Another thing is that the map screen could auto-scroll to were you are, instead of asking the player to press the W or S buttons when selecting an stage.
Very good work! I'll keep playing this one.
