I also got the heavy white noise on the screen, but in the downloaded version it's fine.
Took my a lot of time to realize I can touch the lazers for a short time without restarting..
Also, I felt like the stages were sometimes dividied into 2 stages merged together, so if I failed I had to redo quite a lot of stuff which felt slow. I also missed audio, but since that's a jam it's totally understandable.
I did liked the mechanic, maybe add the ability to stack the boxes and jump on them..?
Overall good game, well done!
