Loved the art. Tremendous stuff. Adorable.
Fantastic soundtrack.
Some of the puzzles were good, though most were fine.
I was confused about which way to go sometimes and didn't realize had to backtrack.
Didn't use fire for any puzzle. Seemed kind of useless as I could build platforms to get anywhere I wanted.
Wasn't completely clear which slimes needed to be stepped on and which needed to be crushed.
Glad you enjoyed the art and soundtrack!
