Great game, I love the idea! I always love games that let you manipulate or build your own environment, so it's great to see that idea implemented here. It worked great with the wizard-y magic theme of the game as well, as did the graphics and the setting, so that was very well done! The different difficulties was a nice feature to see as well, I like the choice that gave me over the gameplay experience - it'd be nice to be able to change them mid-level, but even having them at all is already a great addition. Really nice game here, well done on making it!
