The atmosphere of the game is really well done, I really like how some of the sound effects are used to present this isolated and dark environment, however the sound for the light switching was a little distracting. But while the presentation of the game is decent, the gameplay and level design could be improved upon. Some enemies showed up right in front of the submarine giving me little to no time to react to them; the invisible walls were not as intuitive, and even though there is text indicating when you reach one of them, there were times were I was stopped by an invisible wall and the text did not show up. The idea for the game is really interesting and I would like to see a more polished version of it in the future.
