## Review summary

Users find Retro TD challenging and enjoyable with strategic variety and a simplistic level system. However, many highlight significant drawbacks: a steep pay-to-win model with costly upgrades, imbalance among towers especially in late game, confusing upgrade mechanics, and passive rewards that only work while playing. Players also desire more levels and an endless mode to enhance longevity. Despite flaws, the game offers competitive and nostalgic tower defense fun for fans of the genre.

### Pros

- Challenging and engaging gameplay that appeals to tower defense fans.
- Variety of towers and a tech tree providing strategic depth.
- Simple and straightforward level system with room for strategy variation.
- Enjoyable and competitive experience that encourages replaying levels to improve.
- Offline features that add to the game's appeal.

### Cons

- Game is extremely pay-to-win with expensive in-game purchases required for upgrades.
- Late game towers are sometimes weaker than beginner towers, causing imbalance.
- Upgrade system is confusing or ineffective, with some users unable to upgrade during the tutorial.
- Passive coin and diamond rewards stop working unless the game is actively being played.
- Lack of additional content such as endless mode or more levels leading to repetitive gameplay.
