### 4/5 — Good but I can’t use my SoundFont

*2026-07-19*

I was gonna have fun using my sound for, but I realize this game has a cash grab were they want you to spend stupid money for putting a free SoundFont Pro that I downloaded why… 🥀

**Developer response:** You can access premium features—including the use of custom SoundFonts—by subscribing or purchasing a one-time lifetime Pro license. While the free features are sufficient for most casual users, software development and maintenance incur costs, so premium features require payment.

### 5/5 — Fantastic Job!!!!
