Not to be biased, but great mechanic:) The shop system was complete (in less development time than mine), and the gadgets feels really good to use. I played around with all the gadgets and had a lot of fun with the physics system. I didn't manage to figure out where to go to win though(I teleported through the walls accidentally through my attempts), but I did manage to put all the customizations onto the character.
Really loved the style of the game you managed to create in such a short time. Liked the pixel camera along with the items I could attach. Looking forward to see the game being polished later:) Not much to say about improvements--it's mostly just polishing and future mechanics to add.
Great job!
