### 5/5 — Unique and charming game!

*2025-03-13, version 3.23*

This puzzle game is so unique and I love how it uses the gyroscopic sensor on your device. The controls are very intuitive but the puzzles still get you thinking. The music goes along perfectly with the visuals resulting in a very enjoyable experience. There's even a fun little surprise at the end! I think this game has great replay value and is the perfect mix of calming yet captivating.

### 5/5 — Cant believe I found it!

*2025-02-08, version 3.23*

I played Simian Interface back when it first released on IOS many years ago. Unfortunately like many other amazing apps, Simian Interface was incompatible with newer IOS updates and could no longer be played. As someone who occasionally searches for old games I used to play on app store I happened to type in good old Simian Interface and was shocked when I saw it back on the app store with the devs stating they brought it back. To support I already bought the infinite loop pack and am approaching 1000 levels completed in just a day of playing! Thank you guys for bringing back Simian Interface as a long time fan and I hope you guys have more in store for us since it has been released again!
