A lot of fun, but confusing interface – KaleidoDraw — a kaleidoscope drawing pad Review

This is a fun, relaxing app, but the interface is confusing and buggy. I'm still keeping it on my iPad so it's not a deal-breaker. ---------------------------------- 1. There's no 'Undo' button, so if I don't like something I've done on it or made a booboo, I have to erase everything. ---------------------------------- 2. The interface is vague: There's are two buttons: one with an upright butterfly and one with a sideways butterfly. Huh? The buttons don't make sense and are not intuitive. ---------------------------------- 3. The 'eraser' is buggy. It usually doesn't erase anything. You have to retrace the exact line that you drew, on the exact part of the screen that you drew it. If you have a 50 point design, it can be a big pain trying to erase anything. ---------------------------------- 4. The slider to select the number of points in the design should have a number value, to tell you how many points there are. ---------------------------------- 5. The color selector should let you choose the RBG number values, to give you the exact color you want. ---------------------------------- 6. The button to scan through the color spectrum is cool, but you should provide an option to select the speed at which it scrolls through the colors. ---------------------------------- 7. The layers and background buttons are sort of confusing. Looking at the app and tinkering with layers, I'm still not sure what the layers do and how to use them. ---------------------------------- Maybe you should provide a 'help' feature, to explain what everything does, though the interface could benefit from a little tweaking. But I still am really enjoying the app and can spend a lot of time on it. Once the interface gets tweaked and polished, I'd be happy to spend a a buck or two for an ad-free version.
