This is a city builder/colony builder on a space wide scale where you can go to various planets to colonize. Think sim ant/sim earth and a bit of dwarf fortress I guess (though reminds me more of sim ant tbh even though they aren't ants). Its not ascii art, but its not that far from a modded dwarf fortress art style or sim earth even with how kinda basicly primitive it is. But it does seem gameplay makes up for it.
Onto the game.
The art is primitive as I've said, this isn't a game if you need the best graphics or even ok graphics, its more like a primitive sim ant/or more like sim earth style almost (which I reference that on purpose, besides how it looks) and the game is highly...can't say complex just yet, but huge learning curve and you can go into space and build cities (yes cities) and colonies on various planets.
Here is the link, just expect a very primitive looking game:
https://store.steampowered.com/app/2416770/_Under_Supernova/Its like a 5 dollar game, literally only 5 dollars I believe I paid for it. Maybe it was a little less. So maybe the low price point puts people initially off, but does seem there is a lot there despite the low price.
Its from china, but 99% translated to english and next patch he is going to finish the rest of the translation apparently. Just two menus haven't been translated as far as I can tell. The UI could use work, but hopefully my suggestion to be able to close the inventory screen gets put in, because I think the UI is going to put a lot of people off. I'd even argue and wait for the ability to close the inventory, because its kinda a rather annoying thing. I personally can overlook it, don't think most would.
However, mostly its the inventory menu is the issue with the UI. There are other issues, but simply being able to close it would be a huge (and easy to do) improvement. it takes up the entire left side of the screen almost (like 75% of it on 1920x1080) and is kinda sore on the eyes. If he puts in to close it, it would improve the UI a lot imo.
So, I've had almost 3 hours into this game. I wrote a guide (basics just to get started) and an initial review 20 minutes in. I'm figuring it out, and there is a HUGE learning curve. The way you control things seems a bit wonky, and takes getting used to. Its not very user friendly, but...
The game actually really reminds me of sim earth (not like a eco simulator...don't think? But it does seem to put in the approach of a dynamic environment and the planet seems to change. And something about planets are able to die out or be terraformed? Not sure since haven't got that far). and sim ant in a lot of ways. Its less dwarf fortress to me, more sim ant. While there are similarities to both, the game for some reason still reminds me more like I'm playing sim ant with a little(?) bit of sim earth.
When you clear cut a forest, fungus and grass starts spreading and molds/spores. I cleared a huge forest and some flowers showed up to. Haven't seen wildfires yet though, but the planets can be bombarded by an (evil) species or something thats out to destroy things I guess. I have a lot to learn still.
It may sound like I'm being negative about the game, but I just want to put it all out there. Its not a game if need even just ok graphics. But since this is bay12 and dwarf fortress was ascii, doubt its an issue for most here. Its 2d very basic art with not much to it. But the gameplay seems to make up for it, though how good it is into space and stuff not entirely sure as I haven't got there. Honestly, might find out the game ends leaving the planet and got scammed out of 5 dollars
But the dev said it starts on a planet into space, and can control a ship and stuff...so...I doubt the former is gonna happen.
But from the description, stuff I've read, what I've personally experienced, the gameplay is good if you like indepth almost simulator-like experience. And want something that may (or may not but to me it does) vaguely reminds you of sim ant/sim earth and a little dwarf fortress.
Oh...and...to add
It has Z-levels. Can dig down, can dig up. So that is a thing one doesn't see very often these days.
