Comments on ReactionLab Classic for Android

★★★★★ thb this game is really fun when you find out new combinations ,reactions etc
★★★★★ Great game but is really annoying that at the moment if I'm burning wood (just coz) and it touches the lowest part of the box and I clear the screen (using clear button) and then put some wood down close to where it was it reignites randomly.
★★☆☆☆ uninteresting, uneducated to say the least, not much time it thought put into this game. i have it a good thirty minutes to an hour of playing it and there isn't much nope than some doodling going on with our graphics
★★☆☆☆ Tried c4 and fire, there should not be an explosion 👎
★★☆☆☆ does not work properly on s10. touch screen does not respond properly
