I like the recent update. There is now enough in the game to get a feel for the mechanic. I was able to get through to the end. It took me a few deaths at the start to get a feel for the controls and movement, but then it felt fine. The level layout was a decent amount of challenge for a short jam demo showing off the game mechanic. I'm used to air dash and double jump, but can't think of playing another game with an air glide, and only being able to do the second jump from the glide state. It is an interesting mechanic, and with good puzzle design can be fun. I would add other abilities so the gameplay doesn't get too repetitive, but this does feel like a good mechanic to be part of a platformer's base set of abilities. I like the umber of checkpoints you have, especially for an early demo. It lets the player do more experimenting, without needing to redo the whole level, even if it is short. A bit more explanation/tutorial would be good, but this was decent for such an early state.
