Hey, I've just completed your game, collected all 100 socks and 5 keys! I really enjoyed it so much, it reminded me of the games I used to play on my old PlayStation, thank you so much! If you plan on working further with this game, I would love to see it.
I had a problem with the green fence that surrounds the worm. I didn't see the stairs, so I was trying to get on it by jumping off the roof from the high building. Took me some tries and then I saw the stairs there, haha..
Anyway, amazing game, can't add much of a feedback, except maybe I'd suggest lowering the music volume when playing that bells minigame. Amazing work man, good job!
