It's a decent attempt at a jumping ragequit platformer like Jump King, especially considering the short amount of time it was worked on, but it still felt very wonky unfortunately.
I think all of the basics are there and it works alright: there's a lot of clever jumps and setups you need to work through and while the world isn't terribly exciting as it doesn't offer any interesting hooks or environments to traverse, it still is somewhat fun to jump around.
What killed it for me for the most part was the lack of polish (which again, is understandable given the time).
For one, the charge bar is completely out-of-whack and an outright liar: after testing I noticed that you only have to fill it up to about half-way, maybe less, to already achieve the maximum a jump will allow, as filling it up beyond that to max will not change anything. This is not only confusing but also frustrating as it severely limits the amount of wiggle room you have to precisely tune your strength.
Next, I found that there were a lot of times where you had no recourse but to do a leap of faith, which sucks because other games like Jump King will at least allow you to jump straight up as a means of scouting ahead: in this all you can do is jump up into the other screen and fail and try all over again, which isn't fair.
Finally there were also just a lot of glitches, like times where I would charge up and jump while standing in the middle of a platform away from walls...only to not jump at all: only moving myself to the side a bit would fix this for some reason.
