Damn this game is difficult! But SO much fun! Even though I would die countless times, I still felt the urge to continue playing the game. As some others have said, some kind of checkpoint system would be great (but would totally make it easy mode). Having my item stripped away from me over a simple misclick... PAIN!
I love how the soundtrack fits the game so well and doesn't become monotonous! All the colours pop and (most of the time) the path needed to take is usually self explanatory.
I did spend some time trying to mess around and not follow pathways, which led to some interesting results! There are a few buggy little moments (as mentioned by others); I found at some point I was somehow able to make a double jump during a fall, unable to kill some enemies even though I was undoubtedly hitting them and then they would suddenly die as I moved away. Most of these are probably minor fixes and doesn't really take away from the gameplay or concept of the game.
The humor is enlightening and even though I saw the robots face more than I care to admit, I will most definitely be playing the game repeatedly.
A fantastic effort by what seems to be a fantastic up and coming team and I hope all the best for them!
