Things are progressing nicely. The majority of robot functionality is complete except for some specific field object interactions. Battery management is up and running too. Things are going pretty smoothly!
Below is a screenshot of what is currently level 3 in the offline in-work version (never mind the programmer art). In this particular level you go to your bulldozer friend and swap the battery to him, and he drives over the spikes without penalty so he can push the switch across (using Z to start pushing). Then your jumping friend can press it and complete the level. Teamwork, people. Teamwork!
Keep watching for the debut of the final product!
