Critical bugs block progression: Multiple severe bugs in stage 3 boss fight prevent players from progressing, including white screen errors, invisible arrows, and unresponsive areas. These issues have been reported as game-breaking and some remain unfixed.

External patch requirement is problematic: The game requires downloading and installing an external patch from the developer's website to play properly, which many players find inconvenient and unreasonable. Issues include region-specific patches and breaking Chinese text after patching.

Gameplay is too tedious: The roguelite gameplay is described as tedious, repetitive, and grindy, with long levels and slow progression. Players find the core loop of grinding for permanent upgrades dull and frustrating.

Out-of-run progression too grindy: Permanent upgrades require many runs to max out, with high costs for key nodes. Players feel the grind is overwhelming and the character is too weak without heavy investment.

Price too high for content offered: Players feel the game is overpriced given the limited content, few CGs, and shallow depth. Recommended price is suggested around 20 yuan.

Roguelite turn-based combat: The game combines roguelite progression with turn-based tactics and real-time skill timing. This core gameplay loop is highlighted across multiple clusters as a defining feature.

Permanent skill upgrades: Players earn SP or skill points during runs to unlock permanent upgrades and skills. This progression system is separate from in-run random choices, providing long-term character growth.

Train investigation theme: The player acts as a female investigator or detective arresting harassers on a Japanese train. This thematic setting is central to the game's identity and story.

Random skill choices: During each run, players select from random skill or upgrade cards, creating varied builds. This roguelite feature adds replayability as players experiment with different combinations.

Outfit and costume system: Outfits change appearance in combat and defeat scenes, and there are bonus costumes. This cosmetic feature provides visual variety and rewards for progression.

Patch is essential: Many reviews stress that the official patch is required to access full content and fix issues. Without it, the game is severely limited.
