Fairly generic PT-mod like incremental. Theme could've been implemented better, again mostly feels like a somewhat lazy formatting of numbers but I'll give it a pass since most other games this round are also like that.
The main issue really is the lack of automation in repetitive tasks, then asking you to do those repetitive tasks a ton more times. Getting the milestones is a pretty big menu-navigating chore which was... Maybe fun but also quite frustrating and could've been executed far better.
