Eggys Death Chamber

You control a small character trapped in a single-screen arena. The moment-to-moment play is about constant movement. You use the WASD keys to dodge around the room while aiming and firing your weapon with the mouse. Waves of egg-shaped enemies spawn in, and your objective is simply to survive them for as long as you can. You collect coins from defeated foes, which you can spend between waves on permanent upgrades like better weapons or increased health. The pacing is relentless; the room gets crowded quickly, and the difficulty comes from managing the increasing number of projectiles and enemies. It feels like a tense, scrappy fight for survival in a very small space.
