Hello!
While this is my favorite RTS and perhaps even favorite overall game right now, I have encountered quite a few issues so far. Well, it's understandable.In any case, here they are:
1) After finishing a SP/MP game, the game menu disappears for good until I restart the game. Apparently it still "exists" (?) since a new game seems to start when I just randomly click at the screen, but it's not visible at all. This is quite a bit annoying.
2) There's quite an unusual amount of delay especially in multiplayer games and even more so when I'm hosting a game or there are a lot of players. It often takes like 1-2 seconds before a command goes through, at worst even 3-4 seconds. In the worst cases it's, frankly, unplayable. The situation is much more bearable in single player games, but it's otherwise more fun to play multiplayer. In addition to lag, when hosting a multiplayer game (I only tried once though) some weird error popped up at the top of the screen. I think it was something like "Null - Reference can't be found"? Along those lines. It appeared like 5 times at the beginning and then disappeared for the rest of the game.
3) The UI generally seems a bit... Unresponsive? Even without the lag, in a single player 1v1 on a small map, it feels like there's some "delay" after commands. Well, the market actions (buy/sell) feel generally smooth, but for example opening a new UI element (Hacker Array / Offworld Market / etc.). feels like it takes way too much time and makes me less likely to use those features. Ideally it would be a near instant act to open a Hacker Array. This might have something to do with my slightly slow computer, though, although I play on low settings and meet the minimum requirements... But I have 100 FPS on though.
4) It'd be nice if it wouldn't take so long to show information after hovering over something. It takes like 20 seconds to see what type of colonies the others have founded by hovering over their names, and you can't really spare that much time before finding a good spot and starting initial production. But then again, in some cases it would be better to check what other colonies have been founded before deciding your initial claims. This is less of a problem with 2-4 players (since you can more easily see in the notifications who found what and even keep up with their founding locations). But with 8 players, the notifications get flooded with semi-useless information (first steel mill etc.) compared to founding announcements and it takes too long to view them by hovering over their names. So I'd like the ability to quickly identify a player's colony type without hovering over their name (preferably both on the map and next to their name) as well as maybe reducing the amount of information shared in the notifications..
There's definitely great potential in this game. If these problems were resolved, it would go a long way towards making the game even more enjoyable
