well the levels are ok, can be 10 can be 100 , but the action that the hero does is .. only Mario thing, jumping on chars to kill them , and collecting coins, i wold add something puzzling or more action , something to spice it a bit, the engine overall is good, graphics love it, sound effects loved it , and the rain effects, however the lack of action and music made me get bored, and say in my mind another Mario text platform. hopefully you could follow some platforms and some easy interactions to add,
