I am very new to itch.io but I try

the controls are: 

A and D (or screen buttons)  - to move

Spacebar (or screen button) - to jump

continue on dialogue - E or click any ware

keep in mind this is a demo I have not even fully done anything with it except the movement and dialogue but more will come soon :D

My Youtube sub to me IK there is roblox videos on it but I don't play roblox anymore so expect proper game dev videos soon
