Color Blast: Block Shooter

This is a casual, portrait-oriented block shooter puzzle game that can be played solo and is highly interruptible, making it suitable for short sessions. While generally fun and playable offline, some players report that later levels become difficult and may require in-game purchases or power-ups to progress, suggesting a pay-to-win element. It's a good choice for players looking for a relaxing, one-handed puzzle experience that can be picked up and put down easily.
