Version 1.2.1 has been released. This update adds the option to display icons over powerups and enemies indicating which colour they are, and adds an auto aim gameplay modifier (from the Torontron version, which only uses one analog stick).
Changelog:
Powerup Icons option added in the Settings menu under Visuals.
Auto Aim option added in the Settings menu under Modifiers.
Tallo: Boss health slightly reduced.
