This was a super fun time! I've always really enjoyed precision platformers, so this was right up my alley, and the movement itself felt great. When jumping, especially while not sprinting, you have a great deal of control in the air, which makes landing tough jumps feel really good. However, I do think that, while sprinting, you lose a lot of that control, making the sections involving wall-running feel a bit more chaotic. Overall, though, the movement mechanics feel really nice.
It's also important in this genre to consistently introduce new mechanics that give you new ways to get through levels, and you do a great job of that too, with mechanics like wind, the mushrooms, and the frogs. These ensure that the experience feels fresh throughout, and it definitely did. There are a couple things that make these mechanics a bit harder to figure out, however. For example, the wind is incredibly strong, and it was pretty difficult to figure out how it interacts with the player's movement. Likewise, the cooldown timer with the frogs made it sort of hard to figure out how they work initially, since there was a lot of waiting around for them to reset, which kind of interfered with the fast-paced experience up to that point.
I had a lot of fun with this game, though! You guys clearly have a lot of love for the genre, and it shows in the way these mechanics are introduced. I would love to see some added decorations or visual polish to really make the graphics pop, but it's in a really great spot.
