ThatOtherDev has updated Cubicle Shooter to version 0.4, here is a quote from the source:
Here is an updated version of Cubicle Shooter (not to be confused with Cubicle Shooter City) for Wii.
I fixed a bug that would sometimes allow you to jump before landing and made optimizations to world rendering that have improved the frame rate.
Thanks to the wonders of threading the program no longer locks up while saving or loading. So you can bring up the home menu and go read comments on user pages or something well it’s saving. I made some changes to saving and loading (old game saves aren’t compatible anymore) that should probably improve the speed of it but I didn’t time it so I can’t really confirm that. Loading is fine but saving the game still takes an absurdly long time.
