Hey CreativeMind thanks for trying my game! (Played your 'Loading the game' demo yesterday, really cool ideas in there!) To answer your remarks:
1. I agree that the controls should be shown in game, I plan to make some kind of e-manual for the final release. However on Scirra Arcade there's a small button called 'Game Instructions' where all the controls are detailed.
2. As for the 8-bit music, I wanted to stay away from it. I really like chiptunes and all but I think that's been done to death in retro-style platformers. I wanted to distinguish myself with more moody instruments and darker compositions. There are already 6 songs in the demo.
3. I feel like you probably missed out on the basics of the gameplay... I'd like to know how far did you get into the game (which level).
Did you know there was a Run button, or that you could break the blocks to find Spell Tomes and cast fire spells to overcome foes?
Also I think that my level design and overall quality are much better than the 1000000's other platformers out there...
