This is an incredible recreation of the feeling of discovering strange ZX Spectrum games circa 1990. It's modern, mouse driven and nicely streamlined but everything about the aesthetic is exactly right, from the crunchy spaceship animation to the choice of machine voice.
I did spend a few minutes confused by the interface because I didn't realize the demo started in travel mode and buttons I was searching for were exclusive to combat mode. This is largely due to my fight-the-tutorial instincts but maybe that detail could be front loaded a little more.
