Unfortunately, I don't have Photoshop; I'm using Aseprite right now. I believe both start from 16x16 (https://itchabop.itch.io/stonebase-ui-pack, https://lyaseek.itch.io/minifhumans), but the UI set has elements at different scales. I've decided to avoid pixel-perfect scaling for now, at least during the prototype and mock-up phase. From your perspective as an artist, do you think it looks awful?

You can do the same thing with Aseprite. If you’re in the mock-up phase, I think you’ve made the right choice. It doesn’t look bad at all, especially since the difference is really minimal. Even if you kept everything like this in the final version, there’d be nothing wrong with it! It’s the same mistake I made with my first pixel art game, but I learned my lesson: keep all assets at a 1:1 ratio and consider 9-slice scaling. I’m glad you’ve found a solution in some way—I’m looking forward to seeing the finished game! :)
