Interesting concept, but the random rules changes seem kinda hard to play around. Its quite possible to be screwed from winning entirely by the time the 2nd rule change happens.
Also maybe wanna have a better indication of which player is mapped to which keys, kinda weird to have player 1 be all the way on the right and player 2 all the way on the left after. Small issue tho.
Could be pretty fun with online multiplayer as local multiplayer is kinda flawed when everyone can see each other's inputs (same keyboard).
