Just more of the same complaints from me. Ideally you should be able to restart via the keyboard; instead of just pressing the space key or something like that though, try making it so the game starts by holding down right? (That's what I thought you were supposed to do at first anyhow).
Also the meteorite obstacles tend to be a little weird with them hitting you when they look to be slightly above you. The ones you gotta jump over are fine, but sometimes it looks like you can walk under one when you can't. Great start otherwise!
