This game is very broken, and I've listed out a few things for you

1. The frame-rate is very slow as there's probably so much going on out of bounds, you should only load them into the game when it's their time to come out

2. The enemies are immortal or it takes a while to kill them, please make them easier to kill

3. You need to add checkpoints and a continue option if you die or quit the game

Please take this and add this as a major update, thank you Chilla! I only left a positive review because when it comes to styles I like and everything, it just feels wrong to leave a negative review
