Fun little game, I'm not the greatest at match games, so I actually really liked the upgrade system - helped make up for my lack of skill, lol.
I'm not sure if this genre is established, and this mechanic comes from it, but the way the tokens will randomly reset, instead of descending like in other match games, makes it a little hard to play around combos, but I think the system of shifting the row/column depending on the movement of the token helps make up for that.
I do like how you're competing against the other member, but I don't think I saw a point display or anything until the end of the game - maybe I missed something, I wasn't paying 100% attention to everything else going on while playing, so having I think having the score show in between rounds, to know how you're doing would be a nice feature.
Other than that, though, I don't think I have much else. Thanks for submitting!
