Oh man NO-GFX mode is great. I ran a long run in robo mode, then let it rebirth at level 10,000 while running a NO-GFX mode test. My RP per hour went from 1-2 million to 24.91 million
I've been digging this game quite a bit! Thank you Barbasu for all your hard work.
Two minor bits of feedback: One I never remember to follow up on my investments, so I have no idea which if any have succeeded. Is there a way to track them? Maybe show the result of the last investment somewhere in the investment screen so we can see what happened?
Second, when switching back to Normal mode from Robo mode, all the purchased upgrades (damage, health, crit, etc) are reset and need to be purchased again. This can be a bummer if you don't remember to turn off the time accelerators before switching back so that you have time to buy them again before the waves hit your turrets.
