gnarglF|_|ck i just lost at tier 21 i was so angry that i smashed my fist on the table wich lead to a glass of wine falling off it and spilling the wine all over my light-coloured pants AAARGGGGGL
The rules are quite comülicated for such a simple game but here is what i figured out:
To initiate a combo you have to jump more then 1 platform at once. If you jumped mor then one platform you have to keep up the number of platforms you jump in order to keep the combo going. only 2-3 jumps lower then the highest jumps are alowed before the combo quits. the score of the height is then multiplicated by the jumps you have taken during the combo.
concerning the way to get a high jump i can only say that you have to get a feel for it.
good luck
