Grab passing characters into your cosy lockers and give them ecstasy while extracting the energy needed to grow into a strong little tentacled monster. Infect lockers and spread copious amounts of love and pleasure while unlocking new abilities and growing ever stronger.

Tentikun is an idle clicker-like game where you try to infect lockers, broom closets, elevators, and toilet stalls with Tentikun’s tentacles.

When a character passes in front of one of these you need to quickly grab them into the locker without any other characters noticing else the action will be reported and an officer might appear and seal one of your lockers.

Lockers will automatically pleasure the character and release them when done but you can enter the locker to speed up the process, or to simply watch the lewd action.

Pleasuring a character in a locker will generate Energy and Lust points. The Energy is used to grow new tentacles in lockers while the Lust Points can be used to upgrade Tentikun or even unlock new types of Tentacles.

Your goal is to reach Tentikun's peak evolution by unlocking its pocket dimension where you can customize and play with its harem.
