Glad you liked it and appreciate the feedback. The UI I already addressed in other comments. Have a few content updates ready to push but I'm waiting for the voting period to end first.
As for expanding the game further; I do plan to work on it a bit more when I get back home. Everything is setup in a way that makes it really easy for me to add a lot more content. I do feel like the game is a bit too easy as it is at the moment due to maps being too small so there is not that much use for peek skill and decision-making on who to go after next. There are currently 2 more game over conditions in addition to time out: peeking to close to another player (cheating) and catching the dog (bite).
Was also considering how it would like as a multiplayer game but I'm worried the gameplay for players that are not "marco" would be a bit too boring.
Thanks for playing!
