Catch the Jelly

You are given a 10-wide x 6-tall space, where 4 jellies are running around. There are 45 levels, starting easy, getting harder as you go. Be careful! Jellies go better and better, and you have to keep your skill up with their training level. Alongside leveling, they will soon get the ability to go faster, and do more tricky things, like teleporting, or going totally random. However, all you need to do is to put your finger on the right place. Big rewards are in the way!
