Changes made were pretty substantial.

Movement has been overhauled- no longer do the cubes move by adding velocity. Now force is added. This solves the prototype's biggest issue: clipping. Now, in my testing, it doesn't happen.

A new way to end levels has been added. Both cubes have to make contact with their specified pods to complete the level.

A second level has been made with these overhauls in mind.  It adds new gimmicks to toy with.

The cubes can now die. If one falls OOB or onto specific platforms, it'll explode and the scene will have to be reset.
