This is quite ornate. I played in safe mode a bit, mixing a drink, stumbling around picking things up and (though I haven't a clue why) attacking patrons (bad guys? zombies? I didn't ask questions). It seems like the engine is robust and the movement is smooth. The game didn't seem to teach me to use space bar to attack, or if it did I didn't notice it, but I figured that out quickly enough. It was quick enough to teach me how to interact with other things.
I suppose the main dev advice I have is to try to implement a facing parameter. The act of movement should turn the sprite in a direction, and attacks should be directional. Other than that, this game has humor, a rules engine worth attention, and a very easy onboarding path. I hope it does great!
