Thanks a lot for the feedback JackOatley, I'm really glad that you enjoyed the game!!
I'm happy that it's passing a nostalgia of Pokemon in the game. I played it a lot, and I've got inspiration on how the boxes would work with the Pokemon game.
The stage that you mentioned is the last stage of the game. You almost finished it! =D
If I continue updating the game in the future, I'll put a Stage Select feature, so people can continue the game where they stopped before.
Again, thank you very much for playing and for the feedback!
