All developed by Matt Roszak (Kupo Games). The series spans Flash, Steam, mobile, and Switch.
Start with EBF4 (Steam/Switch/Mobile) — best balance of accessibility, content, and modern UI. Then EBF5 for the full deepest experience. EBF1-2 are historical curiosities (simpler, no equipment/skill trees).
Total: 5 main games, 2 bullet-hell spin-offs, 1 platformer prequel. All worth playing if you love turn-based RPG humor and depth.
