Very nice i love the level design well done and the idea of the wall running is pretty ballsy for a game jam cuz its pretty hard to get right i think it was very close the main problem i was running into was there was not enough buffer for making moves on the wall.
What i mean is while in the air i expect that i will land on the wall and stick but if i let go of the key toward the wall just a little to early than i don't stick and then fall, this is bad cuz if someone were to just jump on and play they would almost never understand this its usually best to make controls easy to stumble into and intuitive so tutorial is just a way to make sure everyone is on the same page. what i would do differently is i would make it so if the player lands on a wall and is looking generally parallel to the wall than activate wall running.
Second is the added press away from the wall to jump farther away i think its best to just say if you press jump you jump of period just to reduce the amount of keys that need to be pressed and in my play through i could only get to where i wanted to go by pressing the opposite key so why not just make it a default. And then when i jump off the wall give me another boost or something cuz if you see in parkour videos when leave the wall the like through them selves off.
For jumping off i would add a small buffer after the wall to still jump this is common in platformers where there's a short buffer after you leave the wall/floor to still jump, you'll be surprised how much less frustrating a simple change like this can make it.
lastly while the levels were well made well a little more telegraphing would be wonderful cuz on the level where you need to zigzag to get to the end i got stuck cuz i didn't see that i was able to go back under the block so some arrows coins, a splash of color or something would be good just so blind players like me don't spend to long looking for something invisible.
In all i enjoyed the gameplay and it was fun! I like the telegraphing to show what was in the level before and what is in now, and I also really enjoyed that the music was persistent usually games restart the music every level/screen-change and it gets really annoying so nice job on making the music not get old, this game has good potential just a little more tweaking on the wall run stuff and and it would be a thousand times better nice job on what you did do though very impressive!
I would very much appreciate some feed back on my game and hope you enjoy and find improvements i could make on it thank you!
