Can't recommend it

It's not that it's difficult overall, but rather, I feel like there aren't enough holes, and I'm seeing that here and there up to stage 13. Each stage consists of 2 levels, and this image is of the harder, second level. Is a puzzle that requires watching a video or using items really a puzzle...? For now, if you move the one on the far right (red) to the opposite end and reinsert it, it wobbles, but since two are already inserted, it just goes back. The only time it seems possible to insert it is at the very beginning, just as the bar starts to lower. I tried several times, but it was impossible to reinsert it on the far left the moment the bar went down. Sometimes, after watching a short video, returning leads to the title screen (this is common in games with many video ads). If you return during a short video while in the middle of a puzzle or when trying to restart with fewer lives, your lives don't decrease... I don't know what kind of life management this is (though I'm happy about it). I thought I'd rather play other similar apps if this is what it's like. Perhaps the fact that the hidden quests aren't super rewarding also contributed to this feeling.
