This was a unique one to say the least xD It is a shame that you didn't have time to finish it up because I really did like some aspects like the picking up, throwing and suspending blocks. That was a neat mechanic with a lot of potential for platforming puzzles! The art was also very fun, reminded me of something along the lines of Little Big Planet!
I must say though, the platforming itself felt a bit "heavy", if that makes sense. It wasn't super satisfying and the character didn't always do what I was trying to. So if that were to be fixed up a bit I think this could be AMAZING!
