This is so stupid! Dont install! I want more elements!

So, I would appreciate if at least some of the other elements are unlocked, before, or after the game is close/or is finished.

I was wondering if you could make a confirm on the clear button. I keep accidently clearing stuff.

It's a lot like Dan Ball. But this is even better. I played around with the free version for like 5 minutes and am going to buy the full right after I post this review. Great job Dev! I've always wanted an app just like this, thank you!

I like it! Quick suggestion, make a toggle able function so particles get affected by your accelerometer!

8 bit graphics bt that hasn't stopped anyone from having fun,has it??

Don. D. May 31, 2014     

I haven't even played it yet, and I know I already like it. :-) :-)

Ten. S. May 20, 2014     

I played around with this free version for a little bit and I had a blast with the limited elements that are given. However, while there was lots of fun of doom and destruction, I feel that the free version is a little too limited. I'm all for supporting the developer, but to withhold all of the fun bits kind of feels cheap. I'm all for paying 99c for removing adds or adding variations of things, but hold back more than half of the game doesn't seem right.

Jen. A. May 20, 2014     

Will buy the full version to share with my 7 year old daughter. Love games that integrate science!

Fer. G. Aug 16, 2016     

This game was fun and had a wide range of elements to use. But now since it's free they take away half of the element that were already there !!! I know it's .99 cents but still I used them before I don't want to pay to use them again. Mabey next time you can add more elements and have people pay for those
