Heyy, first of all, thanks alot for the detailed feedback!
Im sorry you couldnt finish the game :(
Im curious tho, where did you get stuck? Did you get stuck on the right (from where you started) with the separate islands? or the big cave tunnel on the left?
My guess is that you couldnt figure out what to do when you went in the cave tunnel.. I did try to make the puzzle there harder to figure out :P
But ill be happy to assist you once i know the situation further :D
For the jump sound, thats just to give more personality to the player and the game itself (thats just my head canon tho, kel (our sound designer) made it and I just found the sound effect really cool xD)
And again, unfortunately there is no save system if you quit the game :(
I know it is not tha thard to add and we could have done it, but we barely managed to get this much out due to some github issues we faced at the last second. But If you die, you do respawn at the last checkpoints (they are invisible)
Again, thanks alot for trying the game out! Id love to assist you if you end up trying the game again, no pressure tho :D
