Nice game! I like the art, and the wide selection of weapons. I also liked the challenge, but it was more in the beginning of the game, as the game doesn't seem to get much harder past 10-ish minutes. I think it would be cool if there would be more enemies that would appear as time goes on, as well as an increased challenge, as at the moment it feels like the game could technically never end until the player dies. Great work though, keep it up!
