Love your take on blocky terrain like Minecraft, the similarity to Terraria  also is visible.

Here are a few thing I think you can improve:

1) The art style is simple, but maybe a little too minimalist. Maybe try to spice it up with some better art or  textures and that's gonna add an awesome punch to the game ;)

2) I think maybe come up with some background art. The grey looks a little bland right now, but if you want to develop this further, I recommend making some background art :D

That's about it. Nice and loved every moment of playing it. ;)

Love your take on Minecraft. Very creative indeed. Art is also very nice. Well done! 

I like you art. 

I like this 2d Minecraft! Great gameplay! Good job!
