Tower defence being one of my favourite genres and one of my favourite games being Factorio, this is really similar and may grab my attention more than Factorio.
I see a lot of people saying the voice acting for this game is subpar, which I can kinda see why, but in my opinion, the voice acting and VFX and some of my favourite things about this game. I love the voices!

Only bad thing I can say about this game is it would easily be in my top 10 games if it had multiplayer. I would love to play this game with a few friends, and maybe if you could adjust the cameras min and max size. The camera being isometric is great but changing its size I would feel like would give you more perspective of the game / world your on.

Other than that its amazing, the graphics are absolutely beautiful, the audio is mesmerising and the gameplay is easy to learn.

AMAZING GAME OVERALL!!!
