I think I beat it? I got the 3 flowers at least. Anyways, it was a really good platforming experience, my immediate thought like others was like N64 mario. I don't actually know if coruch jumping is a real thing in those games as I grew up with only a PC haha. Either way, I liked the feel of crouch jumping.
The warping tower is cool and really cements the game as a great platformer. Things that seem like your next jump might not be, and I appreciate the subversion. The save rift was a nice addition as well. The style is pretty cool and definitely strange in a the best wway imaginable.
congrats on the release!
