Sometimes 2 tubes are one over the other, or 1 tube and a rat. You could check if there is a collision of objects when you put the tubes and the rats. It's a bit frustrating to time the drop.. :)

Thanks for the feedback, this to be honest is intentional, if they loop, they get better organized again, once tube and mouse are over, you can still hit the tube since its higher, if two tubes are over each other one of them can be hit, so better wait for the loop

Having to time the colours doesn't make it more enjoyable, just frustrating.

And since that's the entire basis behind this game, I'd go try something else.

Hi thanks for the feedback, this is indeed the idea behind the game, timing to hit the tubes with the drop, as you progress tubes get faster and drops as well. don't hit the lab rats dough!

I agree that it was a little too hard. I would also show the ingredients to mix colors in the first few levels.

Hey, thanks for feedback, the ingredients are behind the HELP menu, (question mark "?"), if we made it too easy to hit the tubes, its possible to finish within minutes ;-P

Just keeps locking up on me when I start the game. (IE11)

Thanks for the feedback, OMG what a shame this IEs, will check this out!

Gets slow fast
