You get extra points for giving me nostalgia vibes from the old(ish) show "My Life as a Teenage Robot". I absolutely loved that show as a kid.
I think the idea is incredible, and it works very well. There's really not too much that needs to be done if you wanted to turn this into a fully fledged game (machanic-wise).
A few more attachments here, a few more puzzles there, a little black screen bug fixing ;) and boom, you've got yourself a pretty finished mechanic/game!
I don't really think theres anything that needs "fixing". It mostly just needs some polish, juice, and its pretty much there, full game.
Overall, great game, solid mechanic, and a big hit of nostalgia, thanks for that!
