This project is my tribute to the roguelites and PlayStation-era RPGs that defined my love of games, blending fast-paced, timing-driven battles with the sense of mystery and danger I grew up chasing.I've had a lot of fun developing this game, and it’s been a joy to bring that idea to life. The minigame you’re about to play is just one game mode available in the full release, and your feedback is incredibly valuable as we keep building toward the launch later this year.Whether you’re here for the strategic combat, the nostalgia, or to test your skills against impossible odds, thank you for giving Eclipse Breaker a try. Now go face the challenge, and see how long you can last!
