This was fun! Very charming style and interesting mechanics. I will be excited to see where you take this!
Minor feedback as you move to develop past this jam version:
> Wall jump? Swinging the paperclip after jumping while pressing movement into a wall seems to reset the ground detection, allowing the player to jump again. This wall jump is actually pretty easy and fun to pull off, but I don't think it was an intended game mechanic.
> Spider boss gets a tad repetitive. I did like its mechanics, pretty fun, but with only two moves it did end up dragging on for awhile. Maybe give it less cycles, or add more moves to keep it interesting?
> The string lasso was really fun but a bit hard to 'grab' at first. This is fine, but you could also let the lasso fire out directionally towards the closest pin if one is within range for faster gameplay.
Overall great work for a jam game! I'll be following.
