One star for hijacking my right-click menu and not giving me a graphics quality toggle. That's ludicrous and annoying--and it needs to stop. Leave my right-click menu alone.
Its a neat little platform game but it doesn't have any sound. That makes the experience kind of lack luster.
For a WIP it's a pretty good game. Fairly basic in its design, but very smooth aside from a few hiccups in frames that I experienced here and there. The biggest flaw I noticed in this is the level design, which prompted a lot of running back and forth and, in the case of the block elevator in level 5, waiting around. I also found it to be a bit too basic in some respects, sort of a "Meat Boy: Key Hunt Edition", though I think you're on the right track with the gravity blocks, and adding a few more puzzle elements like that could really make this game stand out a bit more.
This game really has potential, but the controls are so spongy. I really hate when characters continue to slide after releasing the key on a landing.
