Seems like an interesting idea. I like games with crafting systems!
Unfortunately, it feels very unfinished. I didn't have enough resources to build anything, and I couldn't collect anything after leaving the first room.
A few other points to consider:
-There is no audio.
-The background has a different resolution than the main character.
-The Build menu scrolls far too slowly.
-The Jump command seems too floaty--it takes too long to return to the ground.
