I like the atmosphere a lot so far, the sound design is great! The game runs really smoothly as well.
I'd suggest adding a menu in the settings to look at the controls. I've been trying to figure out how to interact with lasers for the last 30 minutes, it's getting frustrating...
Custom controls would be even better but I don't know if that's possible. For instance, I'm on a laptop and don't have a mouse ready, so I had to set up a macro for the middle button mid-way through. Being able to set a function to another key would have helped a lot!
I'm not sure you plan on working on this any further, but I'd love to be able make more progress in the game!
