I have once again made some small improvements (don't expect anything else) but now I will try remembering them.

You can't get softlocked if you have the controls settings set to controller and don't have a controller connected anymore

There are some new things in the background of 1-2

I changed the color of the background in 2-3 so it's easier to see what you are doing (In other words the background doesn't have the same color as the walls anymore)

Now there's an actual reason to try avoiding the fireballs in the last room of 2-3

I finally made myself fix the shovel in 3-3 (Before it rotated in the opposite direction of the direction you try to rotate it (Why is this so hard to explain))

And that is all I remember (It also might be all noticeable changes)

I have also finished world 4 (World 4 won't be playable in the demo by the way)

I want to say some more things about world 4 but I don't have anything to say (without spoiling too much) so I will just put some screenshots here.
