### 3/5 — Too many ads

*2026-05-06*

The game is fun until the ads start. An ad plays after every single level you play, and many times the ad is longer than the playing time of the level. In other words, you can beat a level in 15 seconds then have to sit through a 30 second ad before you can play the next level. There’s no way to remove ads either. So although it’s fun I’m deleting it

**Developer response:** Thanks for sharing this. You were right – the ads were interrupting short levels too often. The latest version includes an Ad-Free purchase that removes banner and between-level ads. We’re sorry this option wasn’t available when you wrote your review.
