Instructions: Z - Select, Confirm X - Skip speech Arrow keys - Move, Jump, Choose - Don't touch white stuff - Stay still to not get hit by blue stuff - Jump on the platforms - Stay alive (until the fight stops halfway through) - Have fun) (also when the fight stops you won cuz' im to lazy to code anything else) Alright, I'll admit Undertale is a pretty cool game to be honest (even though I haven't played it)
edit: I FINNALY PLAED UNDERTALE OMG THIS GAME IS SO GOOD
