Great game! I love the UI. Combining a gacha with a jack in the box is great idea. I kinda wish there were more early game rewards and the clipping on the corners of the box look a little weird but otherwise great job.
I wasn't really looking for more rewards just that the rewards would be easier to get starting out since I've never been too interested in a grindy idle game. I'm not a huge fan of idle games so take what I say with a grain of salt.
