Block Nova!

This is a relaxing, solo block puzzle game played in short, interruptible sessions, suitable for playing one-handed. While generally free-to-play, some users indicate potential pay-to-win elements and a high ad frequency, though it can be played offline and is suitable for new parents due to its high interruptibility and lack of timers. It's ideal for players seeking a casual brain teaser that can be picked up and put down easily.
