Played the game, became a literal god, 10/10. I stopped at 1128 monsters. Very fun game, addicting loop, always a fan of letting the player become INSANE Risk of Rain style.
Only bit of criticism would be the movement, it felt like I needed to move my mouse in certain ways to run full speed; not sure if that was intentional or not (running forward vs strafing). Outside of that, maybe slowing the progression, or upping the monsters based on the character's level to provide a bit more challenge (or at least length) to the game.
Great job!
