Pink Hour

Pink Hour is a free, short prequel to Kero Blaster and also doubles as a demo for it. Having lost an important document, Pink Office Lady goes into the underground to retrieve it before the boss needs it. The gameplay is mostly identical to Kero Blaster, but omitting a few features such as money, upgrades, saving and different weapons. A hard mode is available, added post-launch, which modifies the level layout.

There are multiple endings depending on the difficulty and whether you successfully retrieved the important document.
