Sorry there was no reply to your question until now! In the video itself I faked it because my computer doesn't have a touch screen xD But if your computer does have a touch screen, do note that Google Chrome does not allow touch controls. However, if both your computer and browser support it, you should be able to enable the option. https://mineblocks.com/1/FAQ#touchcontrols

Awh :D It's awesome that Mine Blocks was part of your childhood like that C: Thank you for revisiting it!

I'm porting my games to my Haxe game engine!
