The visuals here are very cohesive and interesting to look like, I could hazard a guess based on the look and layout that this is somewhat inspired by Iron Lung, which it evokes nicely. The game itself seems a little too hard though. Despite getting the numbers very quickly, loading, and firing the artillery, after the third launch I automatically lost before I even had the change to turn back around and continue inputting the numbers. I think with better balancing and a more gradual ramping of difficulty would improve the experience greatly. As a whole, I do think it is very well done. I will also say as a small nitpick, the sort of flickering light sound that plays in the room by default is very grating on sensitive ears and repeats very often, so adding some variety to that might be a good choice. Good job!
