'Ah~ Can you hear me?' 'Sumin's Tower:Session No.5' is a first-person 3D platformer. Climb the tower under the guidance of Sumin, the developer who crafted the stage just for you, and help her create the perfect session. Leap over the platforms and obstacles she carefully placed throughout the tower, master each gimmick, and reach the final goal. Sumin will be thrilled to see your graceful success. 'Be honest—there’s nothing unfair about it, right?' According to Sumin, everything in this session is perfectly reasonable. There are no unfair traps that push you off the tower, no brutally tight timing windows requiring 0.1-second precision. She doesn't want you to fail. All you need is patience and composure. But be warned: If you end the session out of frustration, 'everything resets.' You'll have to climb the tower from the beginning—and Sumin's memory of your time together will be wiped clean. She'll greet you again like it's the very first time. So, before entering the session, make sure you have time... and the right mindset. 'What in the world are you doing?' There aren't many, but you'll encounter moments of choice. Your unexpected actions might fluster Sumin, or even uncover a secret you weren't supposed to find. When the moment comes, will you make decisions for her sake—or let your curiosity take the lead? 'Sumin can see everything you do, but she can't force you.' 'If you feel like hanging around a bit longer, go for it.' Even after conquering the tower, and with no more goals left to complete, you're free to remain in the session as long as you like. There may not be much else to do—aside from practicing your speedruns—but that's not the point. What matters is that, to the very end... Sumin gave you the right to choose.
