Best soothing game

I have been looking for a game like this for a very long time. It is very cute and soothing with nostalgic pastel colors and shapes that soothe me to sleep. It is the best bedtime app when I need something to help wind me down. It’s completely relaxing and idle with nothing stressful like complex rules, time limits, or pressure. Other reviewers found this aspect boring but I find it to be the most appealing part of this app because it is still engaging minus the cortisol spike. There are plenty of stressful games for distraction out there for daytime use. This is one of the few quality games out there that makes it soothing and appropriate for anxiety, bedtime, or any time someone wants to relax and unwind in a safe space and that makes this game a gem.

Very good and peaceful game!

I’ve played this for 2 days now and I am already level 83 sometimes I’d get stuck but I clicked the start over botton and I stacked all of them there are no bugs in this game, however if you guys are wondering why it has ads well every game does so please don’t complain about it, besides they can’t change the ads or put the ads off.

Nice relaxing app

I really like this app. It is simple and a good way to relax for a bit. There are ads after every other session. But, they are short and so not too annoying. I wish there was a way to pay to remove them because I would gladly pay for this app since it is so enjoyable.
