### 3/5 — Worth the free download

*2024-12-04*

The game is pretty fun and you can definitely kill a lot of time with it. It’s also very inexpensive with only a single IAP of $1, which is really nice. 

My only complaint and the reason for 3 stars is because of the lack of instruction or documentation. Maybe that’s supposed to be the point of the game, since you are the scientists assistant and your purpose is to make discoveries and figure it out on your own, but it’s still slightly annoying when you get really stuck and can’t figure out what you need to do differently. Even if the purpose is to get you stuck so you would buy more stars, that would be helpful to have a little popup or something that would give you a hint at what your options are at that point. 

The “no reactions found” isn’t really that helpful since you can essentially move the atoms around, but the part that could include some documentation would be like why sometimes they appear to hit a ceiling and collapse compared to the times when they don’t collapse. What’s making them collapse?

**Developer response:** Thanks for the feedback. As you go through the mission, the professor gives you hints about the behavior of atoms. You may have missed them. All atoms that do not participate in the reaction (atoms without numbers) are destroyed when they touch the bottom of the reactor. Have a good reaction!
