Mr. Sleepy Man is on my 2026 short list for games that look way up my alley, and its release is now just a couple months away. Those inscrutable ’90s Japan-only PS1 game vibes are in full effect in the new trailer, which was released alongside the news of a March 10, 2026 launch on PC (Steam).

A Nintendo Switch version is on the way, too, but developer Devin Santi says it will follow later. Stay tuned for more on that as it’s announced, and check out the anything-but-sleepy new preview below.

Here’s how the official Steam page describes it:

In Mr. Sleepy Man, you play as a sleepy guy who’s up way past his bedtime and out of control!

The citizens of Bedtime Town don’t stand a chance! Make a mess of everything you find and turn the entire town against you!

Mr. Sleepy Man features a fully expressive 3D platformer moveset. Jump, glide, and dive your way through interconnected levels that encourage exploration and experimentation.

Interactivity is key! You can pick up and play with every item you find. You’ll need to use the environment to your advantage if you want to create chaos and find every secret this game has to offer!

Your actions will have consequences! NPCs will remember how you’ve treated them. Friendly faces won’t last long when you’re up to no good, so be wise! 

Bedtime Town’s cast of outrageous characters have their own independent logic. These aren’t copy + paste NPCs. Each one of these characters responds in a different way that reflects their own personality!

Mr. Sleepy Man features an interconnected world filled with secrets for the player to explore. With over 250 objectives to complete (including collectables), you’ll easily get lost finding every nook and cranny this game has to offer.

With a fully original soundtrack composed and performed by the developer, Mr. Sleepy Man delivers a soundscape that blends nostalgic homages to classic 3D platformers with the raw, melodic edge of early 2000s alternative rock.
