Nice simple shooter!
Really liked the game boy visuals, and the wacky idea of killing zombies by making them drunk, there is almost a symbology for achoolism here but I cant quite put it into works haha.
And the upgrades are a welcome addition for variety. The only downsides are that the game might be too short (which makes sense, its a jam game), and when the enemies get to the counter they seems to almost bug out and keep "rubberbanding", and even after killed it seemed they would take 1 hit point away.
But overall its a pretty cool game, if it where to be expended with more levels, upgrades and maybe making it so the zombies did something different when at the counter, the game would be perfect. Congrats!
