In the past 2 weeks I've been mostly working on improving the visuals here and there.

The hub got some more sprites to give more variety. The old version is on the left and the new one is on the right.

I've did a big upgrade to level 4's rendering, I'll probably change the floor texture soon to make it more distinct from the sand. The old version is on the left and the new one is on the right.

and now bullets have a visual effect when they hit enemies or you.
