I had fun playing this game. :)
Took me 3 rounds to finally understand how the token moving worked (I was thinking it was just position swapping, not full column/row sliding) and to start actually playing the game with a workable strategy.
I think adding an image showing the "before and after" of a token move would help understand the mechanics better.
I liked the character art, the UI design and the sound design! Nice music.
Since the tokens that fill up the space left by a token group match are seemingly random, my strategy consisted on never matching tokens that were next to 2 contiguous negative tokens (purple one and the rival one) so that there was a zero chance of accidentally matching them and killing my score. If I got to a point where that was the only move, I'd just press the shuffle button and sacrifice the bonus points. It ended up working pretty well on my second play as Flayon, although I only won by 10 points in the end (that was a close game!)
I lost on my first play as Ollie since I basically threw the first 3 rounds as I didn't understand how the game worked. XD
Great game! Especially considering you worked on it for only 48 hours. (plus the 2 additional days from the grace period)
