This game is very bad for my OCDs, there's always a way to upgrade my automation! I spent so much time just improving what I already automated, and was already working, with slightly better bots, instead of expanding areas and create new automation chains.

Jokes aside, it's a great "little" game. It's very cute and both casual and "hardcore", depending on how well you want to optimize your productions. There are TONS of content, seriously, I'm almost 30 hours in my first playthrough and only unlocked the first 3 levels of settlement out of 8, bots tiers 3 out of 4 and colonists level 3 out of 7.
There are no timers to run after, no enemies that could come and kill your bots, no natural disaster that would destroy your structures, I love it for that, it's really for the automation lovers, the perfectionists who want to create the most efficient production chains possible.
The complexity of programming you can do is quite deep given the pretty simple tools you have access to. However, the game will only tell you about basic things, you'll have to try and figure out the rest by yourself, or look up some guides online.

The one flaw I can find in this game is that it gets pretty grindy, and there is no way to speed up time. I see there's also a modding community, so maybe there is a mod for that, but I don't play with mods anymore, I prefer to experience the game the designers came up with.
Besides that, it's a very good game for people who love colony sims and want to automate everything they can. For 20€, it's a steal, in my opinion.
