This is such an intuitive tool! As an app, I feel like it has all of the features it needs to have, and it's really fun to play around with. Everything feels good to control, and it's super easy to just hop in and do what you need to do.
If I had to request some extra features, I'd love to be able to put text on a cake, or maybe have some kind of free-draw tool to do more involved frosting designs.
This might be a bit more niche, but I'd also love to be able to mass select and copy multiple objects at once. I kind of went with a more avant garde design for my cake that involved a slightly complicated anime eye made out of a bunch of sprinkles - If there was some kind of feature to copy all of those shapes at once, that would have helped in my VERY SPECIFIC scenario. Or maybe an ability to save a group of items as its own custom object or stamp that you could easily repeat. Truthfully, I imagine that would be a feature that not too many people would get a whole lot of use out of, but it could definitely encourage more intense cake designs.
As this is, though, I really don't have any issues with this game - the presentation is remarkably well done, and everything that's already included feels really good and well refined. You've created a great set of tools that are really fun to use! Great job!
I present to you my cake of anime Abraham Lincoln.
I made the cake on stream, you can check it out here around 1:24:00 :P
