Thank you so much for playing!
Yes, it is undone because I'm a noob at making games and I had a week to make it XD
About the delay in shots, that was intentional!(You should HOLD "Space" to shoot and HOLD "W" to jump several times.I should have wrote in the key menu that all of the keys are holdable.Sorry for that :( )
And the cave:That is not because of your PC. That was my problem, I just don't know how to optimize my game.I can add an If statement so enemies stop spawning when there are too many of them.
Again thanks for your feedback!That means a lot to me!
