This is an updated version of Slime Roll.
Notable changes:
The red circles have been removed and replaced with blue ones that are of a consistent size.
If slime comes in contact with a blue circle then the blue circle becomes slime.
There is on screen text that tells you how many blue circles still exist.
When placing slime in the editor you no longer need to press and release the button for each piece of slime.
There is a limit to how closely you can place two pieces of slime together in the editor.
The same rules for placing slime in the editor also apply to the blue circles.
You can now delete whatever object you are pointing at in the editor (instead of only being able to delete the last thing spawned).
The X in the editor has been replaced with a proper reticule.
There is a slightly nicer title at the menu.
All on screen text fills the same percentage of the screen regardless of resolution.
I’ve fixed the problem where there would sometimes be inappropriate white pixels along the edges of circles.
gravity is slightly stronger.
PS3 controls:
Left analog stick = Move the camera
L1 and R1 = rotate the camera and the direction of gravity
L2 and R2 = zoom the camera in and out
X (in the editor) spawn a wall (hold and drag to scale)
Circle (in the editor) spawn a blue blob
Square (in the editor) spawn slime
Triangle (in the editor) remove whatever you are pointing at
