Great work overall. It’s a bit overwhelming at first with text info and visual but after a while, I understood how the game works. It’s a nice concept and remind me a bit of 2048 (the game).
It's my big failing of this game, more tutorial work :). I copped out with the wall of text. But while building the rest of the game I ran out of time really to re-invent the tutorial. Should have had 4 worlds for that to or something.
Glad you got into it though, and hope Hue had a good time :)
