Ultrakill Patch 17d2 Fixes Boss Bars and Coin Tech

Ultrakill receives a hotfix addressing broken secret rooms, erratic boss health bars, and coin-punching interactions. The patch straightens out visual bugs tied to Malicious Faces and Sawed-On Shotguns.

Ultrakill's quick follow-up patch targets mechanical snags and interface glitches introduced in version 17. The update restores consistency to enemy projectiles, weapon behaviors, and stage layouts.

Boss and Enemy Adjustments

Boss health bars no longer squish vertically when multiple health bars display at the same time. Malicious Face beams can no longer direct hit the player, reverting an earlier change, and these enemies now correctly aim at player-ridden rockets. Additionally, Malicious Faces will no longer spam errors when moved via the Spawner arm.

Weapon and Combat Fixes

Niche coin-punching tech is restored, letting players properly punch coins hit by beams into enemies once again. Dual-wield Sawed-On Shotguns no longer break when launching a chainsaw. The update also fixes a secret room in level 8-1 that had stopped working and restores the missing intro warning screen.

Why this patch matters

Patch 17d2 is a quick cleanup that addresses minor regression bugs and restores expected weapon interactions without major systemic shifts.
