This is my second mod, this mod is about to go longest as possible with slowest progress possible (not as Dynas Tree.)
If you want to try the mod go to:
The Research Tree (githack.com)
OR (Recommended):
The Research Tree (difficultcomplexity.github.io)
There are currently 3 tiers or more to go, the more tiers you have the more you can unlock.
This tree is focused on mild speed, from upgrades lengthing from 30s to 180s. Tiers reset everything (as Row 15 is being used)
WIP:
Achievements at V0.3.1
More things soon for Tier 3!
