Heyo!
I really liked the music and the SFX of the dominos falling, very satisfying. I didn't experience any bugs as well which is really dope!
I can see you were solo dev-ing in, if you plan to work on it further after the game jam I'd suggest working on the UI more, the room itself and just adding more levels.
Overall, good work for 1 person in a weeks time and has potential to be really addictive with a bit more polish :)
