So first off, the sound, music, visuals and general vibe of this game are lovely. They really capture the atmosphere of being a super hero (or a super villain). But boy yep this game is challenging, I suspect that this could be one of those games where once you have mastered the controls you can drive that ball around really efficiently. From a new players perspective it might benefit from making the initial levels - less failable. Once frustration I had was that a simple mistake often meant the ball got into a worse position than at the very start of a level, making it better to restart than try and fix it. Adding a quick level reset would help with this - I found I had to route back through a few menus to choose to play the level again. The checkpoint system is a nice idea but again, the game makes you work for it.
So my overall opinion is cool concept but for the noob player like myself it was a bit frustratingly difficult to get into, but that could just be me and others like the difficulty level. Also would it be easy to add controller support too, I think that would be a good choice to have. Keep up the good work.
