Play Sentouin - Yamada Hajime (J)(Rising Sun) Online

Sentouin: Yamada Hajime is a Japan-only Game Boy Advance release from developer/publisher Rising Sun. It arrived late in the GBA's life, a time when the handheld was full of experimental and niche titles. This one fits right in, offering a comedic take on the stealth genre without taking itself too seriously.

You control Hajime, an inept spy sent on various missions that usually involve infiltration and retrieval. The gameplay mixes simple stealth, like avoiding guard sightlines, with interactive dialogue and environmental puzzles. A lot of the challenge comes from managing Hajime's bumbling nature; he might accidentally set off alarms or get distracted, turning straightforward tasks into chaotic scrambles. The objective is always to complete your mission by any means necessary, often through improvisation rather than skill. It feels like barely holding things together while the game constantly laughs at your mistakes.
