first off, thank you so much for sharing your detailed experience and all the nice critique you gave to our lil game!
second, my original intention with this game is to be very difficult and cryptic platformer (akin to hebereke/uforia), having players figure stuff out on there own for the most part and it's why i didn't really add any kind of instructions to the description. however, a lot of the clues/dialogue that told you how new abilities worked weren't added in in this version due to time constraints.
for the part on the right of the map, you are supposed beat the rabbit to unlock the ability to stomp on heads and then stomp on enemy heads to progress further (i wanted to lock out anyone who doesn't have the ability to progress further).
picking up objects and being able to platform on them was intentional and you could choose to jump on the enemies to get back to the middle of the map or use the items to platform over them.
yeah i really wanted to do a proper cling onto a wall and climb like knuckles mechanic, but again we couldn't add it with the time i had. so we just kept in the temporary wall jump we had already.
again, thank you for playing and giving your thoughts on it. we hope to regroup at some point and make this a proper game with the fleshed out mechanics that were missed in this jam AND adding a bigger map, more abilities, and just more stuff.
