Good start for a game! I'm a big Die Hard fan so this one definitely hits the right spot. Loved the art too and the controls work pretty well. However there are some problems too: sometimes the attacks just straight up don't do anything to the enemies and it's not very clear where you can jump on the stairs, sometimes (I think if you jump at a lower part of them) you just fall through. It's also annoying that if you die after getting the first upgrade you have to go through that dialogue all over again. But well done on what you've done so far.
