Game is simple in concept, difficult to win. It does feel punishingly difficult, in that multiple runs I just ran out of time and never found a time increase item, I only actually found one of those once.
There is a nasty flickering effect, I assume this is related to the Web export issues as I didn't try the download. It's gross, and hurts my eyes, but I don't think that was on you.
Enjoyed the game, the audio was fairly loud and a volume control would be nice, but overall well executed.
