I went for a retro vibe with mine
My game is called One Shot In The Chamber, a wave based survival game where you must fight off hordes of enemies with the catch being, you have only one bullet. Fortunately, the bullet is magic and you can summon it back to you or teleport to it. Using this unique ability, you must survive as long as possible in the chamber. Here is a screenshot of the game and the link to the game page: https://mark-auman.itch.io/one-shot-in-the-chamber
