Great job on the game. I really enjoyed the title screens music. I agree with Nardulus on his suggestions, there is always room for improvements. I noticed that when typing in my name there was a little font trouble with little lines showing. Not that big of a deal, but it can be fixed.
Otherwise the graphics are at a decent level. I hope it sells well, and you will create a sequel with some of these suggestions implemented in the future. As well, thank you for the demo!
