Super Cave Boy Nrojt edition

Hello Everyone!
My name is Tjorn and this is my second game I ever made, so don't expect much of it.
It is a platformer.

It was made using this tutorial: https://www.udemy.com/make-a-game-and-learn-to-code-in-gamemaker-studio/learn/v4/overview

I did add some things and all the levels are made by me.

The game supports keyboard, ps4 and xbox 360 controllers. I only own a ps4 controller, so if there is a bug with the 360 controller I might not be able to fix it.
Xbox one controller is and will probably not (be) supported.

To do list:
Fix some bugs with the second boss
Add more levels
Add new bosses and enemies

Bugs:
First try if you can solve it by using windows compatibility mode. If it still doesn't work, please leave a comment with as much detail as you can. If possible paste the crash report in the comment.

All suggestions are welcome. I would like to know what people want in this game. But know that I am a beginner and I am not able to figure everything out.
