First off, great game, gave you high marks haha! I really enjoyed it. At first I felt it a bit punishing and repetitive and I was about to give up but then I noticed that the stage started different so I kept playing and got the hang of it! I loved the simple art style. Not being able to see the terrain was a bit annoying and frustrating but I started remembering where the terrain bits where and found myself getting further. I stumbled on a coin that was impossible to get because the character was too slow, but then I noticed that while you survived longer, you'd get faster so then I got the coin haha! I would add hitpoints and health around the stage and make the collision a bit safer to survive a bit more because I doubt anyone would survive the speed gain haha I think I played this game too much but I really enjoyed it! Great job!
