So first of all...it should not be hate or something, I just want to help you to improve the game and fix some bugs :)
The first bug that I noticed was the Pause Menu. You cant switch or click anything (Windows 64 Bit). The second one was the Slow-Mo that isn't working how it should. It is not activating. The third one was the Grappling Gun that was not aiming at the "blocks" where I aimed at. Or the autoaim of the Grappling gun. The fourd one was smiliar to the first one. Afterwards I finished the Tutorial Level I could not click anything and was not able to play the next level. 
Hopefully I helped you <3
