You put a lot of work into this game and I really appreciate the time you took to make a tutorial. I had to shut down the game part way through the first level after being told to press E because the "Hit space" instruction went by too fast for me to read it, though when I reloaded, I did catch the instruction and was able to continue.
P.S. Not sure if you have seen GoedWare's recent email, but we now only need 6 rating as opposed to ten and I think this is your 6th rating :)
