First, thanks for a great game!
My #1 high-scrores for different ground-only maps seems to have been deleted :p
Most ground-only maps can play almost indefinitely if you figure out how to deny new waves from entering.
Ive added a screenshot of Field of Broken Dreams (ground only) showing this.
Quick explanation :
- When direction is right act as release point to lengthen time to base
- When direction is up act as diversion point (used after shifting to up) to lenghthen and clog up queue
3.Release point (used after shifting to up) to recycle mobs
4.Release point to fill up "the tank" (used on the end of the up queue to also shorten the up queue)
5.Deny areas. Mobs from right will have preference and deny leaks from "the tank" and new waves
To get the score just takes time. I think this was about 5 or 6 hours, and 1 mob killed each ~5 mins.
