i didnot understand the game
That's understandable...
The black block has a light that casts shadows.
The white block can only exist in those shadows, and if it leaves the shadows, it will die.
The goal is to retract the spikes and get the black block onto the 02.
Unfortunately, we didn't get to test the map before we submitted so there are some game breaking bugs...
Sometimes the code that checks if the white block is in the shadow will break and you might die for no reason.
The walls get rendered on top of shadows, and it blocks the button that retracts the spikes.
The button that retracts the spikes is hidden underneath the bottom left gray rectangle.
So sorry about the bugs. Although it wont help my chances for the jam, I plan to release a fixed up version of the game soon.
