Okay so first of all, I really like that there was a story and with a plot twist and backstory with rope and pickaxe tutorial. It's metroidvania (I think at least, to me it seems like that), which I really like.
Boss fights were really cool and interesting too, each unique.
Also R to retrieve wooden plank is kinda hard when you are going right, imo it would be better on like shift or ctrl maybe.
Rope sometimes felt a bit uncontrollable though it was doable.
Overall, really fun game, well done, it's kinda long for game jam too imo. Good luck :D
