It looks like a game. I could only move left and right, despite 4 way controls in the description. It overheats my computer and then stutters. I was only able to play for a few seconds. The boxes were moving very slowly and were very easy to avoid.
Cheers for the feedback! I'll change the description to only include two way left and right controls, that's a typo. I'm quite surprised it overheats your computer though, I haven't had any issues with players saying that it can't run. Do you mind if I ask what hardware your machine has?
