Really impressive work on this! I played this after watching it on Vikfro's stream. Enjoyed going through it, but didn't get as much of a fear / anxiety response as some similar games. I liked how you incorporated the theme. The scale of what you made is impressive for the length of jam, too.
I appreciated the attention to detail on to the atmosphere, the interior submersible design, the enemy animation, and the level design. I wished I didn't have to stare at a throttle while operating it, and could look out the window instead. I had some conditioned response from other games to try holding right-click to see if it would free the camera movement.
I know from the stream that you worked tirelessly on this. I hope the experience itself was rewarding and inspiring, and that you aren't setting too high expectations on overall reception. It's a solid game. Congrats to the team!
