Mushihimesama (2004)

A small hitbox lets you thread spaces that initially look impossible, and learning when to move calmly feels better than simply surviving by luck. Start with the Steam version's Novice mode, then compare progress under the same mode and settings. It includes stage training and configurable controls; the optional version 1.5 is a different ruleset. This is a focused dodging project, rather than an invitation to jump straight into Ultra.
