Very cool idea, the execution could be better, but for 72h it's still very good. It gets very easy after figuring out the basic mechanic, could use some more advanced lasers later on (or maybe I didn't get to any).
What made me stop playing was the controls - there's no clear feedback on when I can jump again, which resulted in me smashing the mouse to make it finally jump :P
I don't think so, I was clicking and nothing was happening, though it did work a lot faster sometimes - might be some timing issues, I've only noticerd I forgot to time my flies when my wife played my game and it was much faster on her PC - a basic mistake, but I missed it anyway.
Have you tried it on other machines? And with UE4, the build can vary a lot from what is going on in the editor (I can't remember if it was UE4, but I think so).
