Keep the classroom simulation under adult control
Use Koin only as a teaching variable, show which states are simulated, and do not gather payment details, credentials, or personal student data. Give instructors a clear way to reset, demonstrate, and discuss fairness, accessibility, and production limitations.
Prove that declining leaves a complete game
Play the advertised core route from the first meaningful action through recovery and its promised conclusion without opening the offer. Record any place where storage, pacing, difficulty, retry access, story information, or social participation feels intentionally weakened. Decline the item at several natural moments and confirm that progress continues from the same point without repeated pressure. Then buy it and compare the owned experience against the free route: the item may add expression, bounded content, or reasonable convenience, but it must not reveal that frustration was manufactured to sell relief. Remove guilt, countdowns, loss threats, and language that treats a voluntary choice as required.
Finish the free path first
Play the complete promised game without opening the offer. Progress, recovery, and the core ending should still feel intentional. For educators and student cohorts, the experience must treat Koin as a teaching simulation and keep adult/institutional review in control.
Offer an easy decline
Give players a visible dismiss action and return them to the exact game state they left without repeated pressure. For educators and student cohorts, the experience must treat Koin as a teaching simulation and keep adult/institutional review in control.
Do not sell relief from frustration
Avoid slowing ordinary progress or creating unnecessary limits simply to make the voluntary game item feel required. For educators and student cohorts, the experience must treat Koin as a teaching simulation and keep adult/institutional review in control.
