Well, the game does deliver on the premise. It's way too short of a strip rock paper scissors game, but given the source art material, I can see there isn't a lot of clothes to work with.
That aside, the biggest weakness is, it's just flat. The only dialogue is at the start and end of the game. I'd say a big part of an enjoyable strip game is the interaction between the player and opponent, but in this case, they only seem to come to 'life' when they finally win or lose.
While I'm unsure if you can do much to extend the length of the game, due to lack of clothing, it could really do with dialogue between the player and Maya to help make it feel a bit more alive.
