With the end of his high school career approaching, Kyou Koyama is a friendless and troubled young man. However, having recently taken an interest in hypnosis, he supposes he can salvage his relationships with his classmates using the power of suggestion. With the help of a modified penlight of his own design, he sets out the change his world, one class rep at a time...

Penlight is a visual novel set in a high-school with a heavy hypnosis and mind control theme with a fair bit of kink sprinkled in. While still in early development, the current release is fully playable from start to finish. It should be noted that all characters featured in the game are in their senior year of high school and are over 18 years of age.

The content overall is very tame with regards to sexual stuff, to the point where the mind control in itself I reckon is about the only mildly titillating thing in there. Still, I think what's there will be enjoyable to some people on this site~

Support The Project:

Penlight is very much a work in progress. Over time I intend to improve the game's writing, art and audio into a more complete game with multiple story branches and additional choices that yield interesting consequences for the player. Check in every second Saturday of each month for a new public release with updated content!

While I'm confident I can make a functioning and enjoyable visual novel on a super limited budget, any funding I do get will be invested into making a higher quality product. If you would like to make a contribution, please visit my Patreon and consider pledging ($5 and over patrons get access to new content up to 4 weeks ahead of the free releases). You can also make one-time donations via my Itch.io page.

Comments and feedback are welcome, too. I appreciate any support!
