Currently we have 1 team member on Freeplay, and 2 on engine changes/ design for future levels.
Note that formicarium levels take significantly longer to complete than Freeplay since Freeplay reuses art assets that already exist and has very little of its own artwork, whereas for the levels we are designing entirely new species, ants, flora and sound. This means hefty recording sessions with our voice artists and getting that all integrated properly.
So Freeplay is an efficient use of time for one team member right now - and his list of things to do before we get it out is now very small.
