Nice graphics and animations, easy to understand, not predatory as other games in the genre (but it counts too much on ads for rewards). Overall a very good experience.

New way to play the genre. I love it. Keep with updates. I can confirm that cloud saves DO work lol

Purposefully hard to get you watching ads for revives and extra coins. It's also nothing new or genre defining.
โ˜…โ˜…โ˜†โ˜†โ˜† Deshon Bell ยท Jan 13, 2025
Been like 5 days and still can't get past the first stage after the tutorial. Is it going to take a year to get past 2 levels?
