Really nice game! I adore the artstyle and I think the mechanics are nicely implemented. A shame you didn't manage to make more weapons and upgrades, because the game already feels quite addictive :d Also I feel the beginning is a little too slow in terms of pacing. Right now it works, because there overall isn't that much gameplay, but in a full game it would be a bit frustrating to kill enemies and get XP so slowly at first. Overall a solid entry, good job!
