New role update! — 你救世主播？ Steam update #994700

1. Updated new characters: Snow Milk Jelly, Nira, and Starlight Kairi2. Added a starting event, where random characters may enter your room and provide various buffs during the second round3. The spawning logic for summons has been adjusted. Now, most characters with special weapons that are summons will generate new summons directly at their character positions (some unfinished parts will be updated and refined later)
