I played until about 400 meters. It was pretty difficult at first until I got into the pattern things usually break down. I'm a big fan of Barotrauma so I enjoyed this familiar experience. Theres a really great mix of mechanics that keeps you moving constantly, and the slow darkening background is very ominious in tandem with the sound design. I think I found a glitch? If you repair a hole / use the pump and keep the key pressed as you walk towards a broken engine, it will instantly repair with no waiting.
