I see, yeah you're right on the gameplay loop changing a bit if I do that 🤔.
The item ideas are really great, and I think you're right on calling them out, they'd be great additions to the game!
Shrinking AND growing, huh? Hmm, if I add a story element with simple missions to fulfill, maybe I could add an element of collecting key items that can only be found at different scales and give the player the ability to change scale themselves, as well as incentive!! (Metroidvania-esque progression design)
You've given me the best feedback so far! Thank you very much for helping out a lot, you're the best!
