There is actually an increase in difficulty as time increases, I just unintentionally made it a lot longer to increase. You can notice the increase when you reached 40. I've noticed during development the spam and camp thing, I still left it in because I thought it would be fun if you found it midgame and just use it to cheat the game. Lastly, I thought the rotation of the character was funny and would be less interesting if there's not much movement in the game at all. Still, thanks for your feedback and I hope you had fun playing my game! :D
