Probably this level (aftersummer) was made only for testing, but whoever created it is a sadist. This level is sick and I enjoyed it.
Especially the Ninja Kitty is fun to fight, a great new enemy! - However, they’re not so much fun anymore after you found out you just have to keep close to it and the ninja won’t harm you anymore. Maybe make it slash when you’re close, too (with some delay, perhaps, so it doesn’t get too hard - or even cooler would be a kick that keeps you at distance without doing damage).
The wart flies sometimes make you “jump” higher than seems reasonable… it feels wrong, really.
Maybe rather a bug: frogatto sometimes gets stuck on those moving chainway platforms (happened to me especially on the second one - he can jump, but not walk) and more rarely, frogatto seems to fall through a platform when jumping on it while it’s moving upwards (especially fourth platform).
Anyway: I see enjoyable challenges coming along…
