That Steve over there is fake. (as of now)

I have to say, the game looks pretty impressive as of now. You may want to change Steve to something else to avoid copyright infringement, though.

You're right. I will change him to something else once I start working on animations, but I'm focusing on collision for now.

can I beta test?

You should zoom the cam out a little more, this will make it a bit more comfortable. Also, maybe make the touchscreen use the mining/building, take Terraria 3ds for example.

Derp- I will try to make an actually good looking version then sure. Talen- The engine that the blocks are scrolling on is where 150 sprites get update to the current sprites internal position variable +current x-y position- modulate (current sprite size).This is then updated for every sprite to change costume once time is given. I wouldn't know how to add more without it being too laggy.
