A cute, neat and charming puzzle game that reminds me of slide puzzles (but done good).
*I played in the desktop version
So first, technical issues or well bugs and stuff like that:
I didn't seem to find any bugs or anything of the sort so congratulations on that.
Now for feedback:
More of personal but the transition between scenes (the box opening animation) feels kind of slow so I would suggest speeding it up slightly.
Other than that I don't really have any gripes or anything I would say its "wrong" or "needs improvement" for what its there.
Overall, good game that I can see it expanded into a full release if you were to ask me.
