Great polish!
I continue to be impressed by the production quality on this game. The visual design is top notch and wrapping the level design in the periodic table is a really creative touch. The sound design is good though perhaps a little loud at times. I like the options of having multiple soundtracks to listen to as well as I play.
The level difficulty seems to ramp up at a good pace with early levels letting the player have some time to learn the somewhat quirky controls.
It seems almost every element in this game has a little touch of occasional animation that really just makes it a joy to play. Each level has something new to watch and avoid and the shapes the obstacles and structures make on each level are interesting aesthetically.
My only complaint really comes down to the finicky controls which can be unresponsive at times regarding jumping which I lead me to many accidental deaths which can become frustrating. This is made more apparent by the game being in the precision platformer genre where it is my belief that responsive controls are a must. I believe a lot of the issues regarding the controls have to do with the players individual keyboard design though as some won't experience this problem.
Great job though overall!
