### 5/5 — Lotinha

*2026-08-21, version 2.0.4*

Hight the best

### 2/5 — Constant ads for apple’s Game Center

*2026-08-21, version 2.0.4*

I’d be willing to pay the $10 for ad-free, but I hate these reminders about the Game Center every time I open the app. They’re just another ad in a different format. When I’ve turned down this reminder 10 times in each of 5 games, take the hint and stop harassing me with these ads.
