Melatonin is a rhythm game about dreams — from Half Asleep, the studio of solo developer David Huynh. It’s the anti-Dance Dance Revolution: no arrows, no intimidating overlays, no timing meters — just hand-drawn pastel vignettes where you tap to the beat of what’s happening on screen. Officially it exists on PC, Switch, and PS5 — no official mobile version — so the Android and iOS builds on this page are mobile ports.

Why people love it
Every level is a different dream about the main character’s life — anxieties about work, dating, social media, the small hours — rendered as a playable music video. The rhythm prompts are integrated into the scene: you’re not hitting abstract notes, you’re tapping when the coffee cup lands, when the phone notification pops, when the elevator door opens. 20+ levels across 5 chapters, each with its own visual style and musical identity.
The rhythm design
- No visible beat bars or note highways — you read the animation itself
- Practice Mode — walk through any level slowly before trying it full-speed
- Challenge modes and Mashups — post-game remixes that combine two levels’ mechanics at higher difficulty
- Level editor included — the full community workshop from the PC version
- Assist options — generous timing windows if you just want the vibes
The mobile port — a natural fit
Rhythm games belong on touchscreens, and Melatonin’s one-tap-one-drag control scheme maps cleanly:
- Whole screen is the controller — tap anywhere, drag where the level asks, no on-screen buttons covering the art
- Runs on modest hardware — it’s a 2D Unity game; even older phones hold a stable frame rate
- Runs offline — fully playable without internet after installation
- ~2 GB installed
Important for any version: use wired headphones or the phone’s own speaker. Bluetooth audio latency ruins rhythm games generally, and Melatonin’s subtle prompts especially.
