I like this game but, it has a lot of weak systems.

Positive:
1. daytime system is good developed and interesting
2. workers system also good

Negative:
1. buildings developed in stupid way, u just putting them like decoration, stupid system when singe factory give 1 coal per n time but if u build 5 factories it just add productivity +~70%
2. Level up system very poor, it's not changing gameplay just adding some more resources at start, stronger workers more buildings or slots unlocked
3. session and contract based rounds, it's not good when you just need to finish a round to start it again to get new contracts and level updates. I start to hate this part, bcos starting again and again, from start to be able to get +1 level.. I go down for 800m but get only +1 level, i go down for 100m get +1 level again
4. very weak system of weapons and upgrades for it
5. need way more skills, weapons and updates for them

The arcade part is good, but player need something new all time, starting again and again it's not good idea. Grinding, skills, weapons mechanics are too bad. I'm adding positive feedback bcos it's rare game and love it, hope for next part will see some god RPG updates

Perfect solution (my vision):


1. Real time level up
2. Big skill tree with different bonuses and combinations
3. Add some heroes for support workers or at last adding some passive effects
4. make platform wider, and put all building in single row, or make some more logical platform
5. make some people amount based logic for factories, for workers...
6. Real time digging for main base while enough coal for core
7. Some guild for getting real time contracts

Needs more stuff

Great gameplay idea but with super awful tuning. The game requires you to fully concentrate the WHOLE 30 MIN from being attacked because the price for losing any resources or a tiny mistake ruin the entire 30 min playout. The game is polished with zero information (bug spawn time, bug's visual range, damage indicator, enemy type for next wave) so that you can lose easily.
TL;DR: Suffer to handle everything and the game is trying to discomfort you. This is not enjoyable and pretty tired.
