Great idea for a game and nice polish. Didn't see the overpowered theme tho.
Few things I noticed:
-Not all modifiers work correctly.
-Had too many turns with 0 moves available in a row (Had like 4 in a row)
-Not being able to choose what side I would like to place my dominoes was a bit annoying.
Other than these few things I have to say I thoroughly enjoyed myself. In my top 10 favourite games list.
Well done on what you managed to get done in such short time.
