Each stage was incredibly fun because the sprites, the music, and even the direction of the gimmicks were all different every time.
You wrote that this was your first serious platformer, but this is definitely one of my favorite games.
Especially in the later stages, I could feel that you’d grown more accustomed to building levels while I was playing.
One thing I noticed was that using C + down to pick up items felt a bit confusing, and the waiting time for the moving platforms that go up and down was a little long.
My favorite stages were the Pyramid and Heaven, meow! (=^･ω･^=)
I also recorded some gameplay footage, but it was captured from an older version.
