Thanks for following up, Yes A grid to display the costumes would be for the best. Being able to click on a specific costume would be more user friendly than pressing a button repeatedly. Probably should limit it to 20 or so costumes per page to avoid a small UI.
Currently the camera system works without major issue, but at low zoom it feels centered awkwardly, and a little higher will have you scraping the ceiling. If smooth zoom would cause issues for players on controller then it's probably fine to leave it as is. but if most people play on mouse and keyboard I think it would be worth implementing.
Overall I love the changes in the latest version. It's a big upgrade from when I wrote my initial review.
