Thanks for the constructive feedback!
I was in quite the time crunch since I had school and other stuff to work on, and therefore no sound and not very thought out level design since i did all 3 levels the last 20 minutes. I would've loved to do some interesting level desings with a camera follow and such, also tweak the movement controls a bit more, like the jump buffer, but unfortulately I hade no time. Glad you liked the tutorial though!
Thanks for the feedback once again, I will take the info and maybe improve this game or definitely other games in the future .
