BETA Osu Mania Tester

BETA Osu! Mania Tester: A Creative Rhythm Game Tool

This is not just a player; it's a dynamic osu!mania testing and creation environment. As a specialized 4K rhythm game tool, it introduces a unique dual-control system perfect for collaborative play or pattern practice. One set of keys (E, R, U, I) controls the generation and sending of notes, while the standard hit keys (D, F, J, K) are used to play them. This enables real-time charting and playing, either alone or with a friend.

Features for Mappers and Players

Co-op Mode: One player sends notes, another hits them. Adjustable send delay for solo use.
Auto Modes: Toggle auto-note generation (Q/W) and full autoplay (Z/X) for convenience.
Optimized Play: For the best experience, use fullscreen and keep "ghost tapping" enabled to prevent input issues.

Ideal for practicing osu! mania patterns, testing song ideas, or enjoying a novel twist on the standard gameplay, this beta tester offers a unique take on the familiar key rhythm game formula directly in your browser.
