Fellow snake climbing puzzler!!!
Phenomenal puzzles; from the elegance of the level design, it's clear that you playtested these meaty levels well! I played the first half of the game holding the Scale key instead of tapping it, which meant that I was playing hard mode and only able to climb 1-high blocks! (...now I'm imagining you get an upgrade that lets you scale higher halfway through, hehe..)
It was a bit awkward to switch the parity of the snake at times (sometimes easier to just restart the level). I think if you throw on your own sprites and music you'll have a super polished game already (:
Thanks for your fantastic game! Loved the reward screen <3
