Love these types of games. This one looks promising, although I haven't played much of it due to random systems being incredibly laggy and I am unsure of what is causing this.
Thanks for checking it out! I almost guarantee it's the background nebula assets tanking your frame rate - I can add an option to the menu to disable them until I get a more performant solution :)
If you redownload, I've added an option to disable nebulas in the options menu, which you can access either from the title screen or in-game by pressing escape, then clicking the button labeled 'options'. Hope that gets it running better for you :)
