solid game, runs with absolutely no crashes on my Zotac RTX3060, even when I do some real sketchy shit. With the recent updates, it is possible to even add your own materials, albeit the UI for it is a bit unintuitive and confusing, and worst of all, you only have per-save materials meaning that you wont get your custom materials on your other saves.

Performance Absolute amazing game on my NVIDIA laptop but for my main PC it is a different story. I cannot believe that this guy has had 13 years to work on said game and still has not made a proper version for AMD graphics cards. I would play this game even more if it had support for AMD too, no offense to this guy though, the game disregarding is overall really good and I think would be worth the $20 bucks. Gameplay I would also like to mention there is not enough materials to have fun on this game for a long time, for example, I have not been able to find a way to simulate an atmosphere. Smoke, and water vapor just turn straight back into water instantly and air is unable to be affected by gravity in anyway. I really wish it had support for multiple bodies, for example, two different celestial bodies should be able to have gravity on each one of them and if possible, it would be amazing to have orbits around stars or similar. Overall Rating Even in its early access state its pretty good, but there are many things that can be improved and do not buy the game if you have not checked out the demo, I hope it improves heavily over time and it becomes more fun to play with. My overall rating? I would give it a soild 6 out of 10 and I recommend you buy it if you are sure that it works good with your system.
