Play Now

https://nostrapps.github.io/melrise/

Tap or click to drop blocks and stack them as precisely as you can. The game runs entirely in the browser with no install required.

How to Play

1. Tap / Click / Spacebar to drop the swinging block onto the tower
2. Align it as closely as possible with the block below
3. Misaligned portions get sliced off, making the next drop harder
4. A complete miss costs you a life (you have 3)
5. Land perfect drops to trigger combos and regrow your block

Scoring System

Action	Points
Normal landing	25
Perfect landing	50 + (streak - 1) x 10 bonus
2x streak	"NICE!"
3x streak	"AMAZING!" + block regrowth begins
5x streak	"ON FIRE!"
7x streak	"UNSTOPPABLE!"
10x streak	"LEGENDARY!"

• Perfect threshold: landing within 5px of the block below
• Block regrowth: at 3+ streak, your block grows back by 15px per streak level (up to the original 200px width)
• High scores are saved locally and can be published to the Nostr leaderboard

Levels

The game progresses through themed levels, each with unique colors, music, and increasing difficulty:

Level	Name	Goal	Speed	Start Width
1	Foundation	10 blocks	0.8x	200px
2	Skyscraper	15 blocks	1.0x	190px
3	Stratosphere	20 blocks	1.2x	180px
4	Endless	Infinite	1.0x	200px

Each level has its own C64-inspired chiptune track played via MOD/XM tracker files.
