At first, I thought you would die when the number countdown reached zero. I later realized that the countdown actually reveals the coordinates instead.

If the game gets expanded further, I think it could be interesting to add something like a radar system, allowing players to calculate the opponent’s coordinates and fire more actively and strategically.

The overall art concept is great. Good game!

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!

Cool game concept, but I was simply too bad at it — really difficult. I do like the PS1-style visuals though, and the dark atmosphere comes across really well.

Is it intentional that the mouse cursor constantly drifts downward?
