This is just from my experience and I don't speak on behalf of anyone else.
Pros:
+ Very cute looking little game.
+ Nice color pallet and graphic style.
+ Simple UI

Cons:
- Map design is confusing and a little overwhelming to look at..
- Building placement is a bit iffy because the layout of the map is not friendly with space.
- Game runs your CPU at 60% and your GPU at 100% (I have 1080ti and an i7-7700k).

Did not find anything majorly wrong in the 45mins that I played it. It's pretty simplistic and what you would expect.
Just needs some optimization to bring down that usage. Gave it a thumbs up because these indie devs are doing a great job and they have something going here. Cheers.
