Thanks for the feedback!
I agree the platforming isn't optimal. Originally the idea was not to emphasize the platforming rather than the puzzle aspect, but there's hardly enough mechanics to work with puzzles as it is. Lets see if there's some new ideas for the future. I might revisit the platforming code as well to make it feel better.
You are also correct about the snake. It's currently very unforgiving and challenging. I had a plan to bind the difficulty data to a level but I didn't have the time to do that. Then it would be easier earlier and get gradually harder, now it's always the same, which is hard. :) But, it's just some additional code and it will be a better experience!
Cheers!
