Very fun game!!! It took me a while to figure out how to get past the first ledge I couldn't jump, I thought I needed to jump and then shrink my neck to increase my jump height, but after a bit I figured out I could hook my head over high ledges to fall sideways onto the places I couldn't jump. Very nice mechanic! Each upgrade was very fun to use and the challenges were very fun to solve, I especially love how you included playtime and completion percentage in the credits, makes me want to play again!
I did complete the game with only two abilities but I thought you could collect three. I was able to get to the exit with just the screwdriver attachment and the claw attachment, not sure if that was accidental or if the third attachment is for bonus content. Anyway, looking forward to trying it again and I hope you are able to add more when the jam is finished!
