Very funny and nice overall presentation!
There's a few things I would have liked better on the visuals side though. The coins at first glance look a lot like a fireball so I keep instinctively trying to dodge them when they are flying at me lol. Also at first I totally didn't notice that there are words on the vending machine and there were supposed to be your upgrade choices, I just walk up and press E randomly lol.
Nice overall game though, but I do wish it was a bit harder.
