This game was more on the simple side but fun regardless! It could have maybe profited from some more pickups, walls, etc. to add a bit more strategy as for me the gameplay mainly consisted of running from corner to corner. I also ran into the issue others have already mentioned that the arrow keys moved the screen, maybe you couldve bound the arrow keys as well as WASD for the movement so players can choose their prefered movement style. I also loved the background art, it wouldve been great to have that in the game itself too but I am assuming you ran out of time to implement that.
Overall I thought the game was fun and I think with just a few tweaks it has a lot of potential! :)
