Great entry, extremely well polished for a jam!
My main complaints are around difficulty, the section returning from the dash pickup and on the section on the way to the double jump pickup took me waaaay too long. I had a hard time going from wall jump to dash, might just be a dexterity issue. Those little blobs are such a pain! Getting up out of the shaft was very irritating, it seemed like the way to do it was with a double jump to get around the edge, but in the middle there was a screen transition with a short but significant pause as the screens loaded; somehow I did this fairly easily the first time, but when I returned I had difficulty getting the timing right, maybe fatigued by then. It really couldn't have been that hard if I could finish it with my limited action platforming skills, though. I finished with 12/16, I went back after I first encountered the boss to pick up a few more to make it easier.
I had no idea there was a wall jump available at first, so I was stuck until I read the comments here mentioning that.
I played through the difficulty because the presentation was so strong. Graphics, animation, music, atmosphere, a bit of humor, all great. Well done, team!
