No idea how I ended up here but very happy that I did! Great job! Many remakes or renditions (of one of my all-time favorites) are simply horrible. Yours however immediately caught my interest and couldn't stop playing (until I reached the end :-( ) . It seems you have every aspect covered from the physics and game play to level design and creativity. Great work and I look forward to the full-version.
My only suggestion would be to include a "mouse sensitivity option" if that is possible...not necessary but would find it helpful.
It could be that it is way too early for me so disregard if this is the case but the keyboard controls didn't seem to work for me. The only button that worked was to show high-scores.
