Comments on ReactionLab Classic for Android

โ˜…โ˜…โ˜…โ˜…โ˜… thb this game is really fun when you find out new combinations ,reactions etc
โ˜…โ˜…โ˜…โ˜…โ˜… 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.
โ˜…โ˜…โ˜†โ˜†โ˜† 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
โ˜…โ˜…โ˜†โ˜†โ˜† Tried c4 and fire, there should not be an explosion ๐Ÿ‘Ž
โ˜…โ˜…โ˜†โ˜†โ˜† does not work properly on s10. touch screen does not respond properly
