My movement keys keep getting stuck in this game (also in some othes). Can anybody who encountered and solved this problem please PM me with the solution?
I think it would be better if you took the money and star bonuses out of the Premium package. They make the free levels way too easy. Levels 13 and 14 are still well-balanced and provide a good challenge.
Tactics to win everything: Starting from the back, fill all good spots before leveling anything to 3. Have a mix of melee units and at least 2 types of mages. When screen is full, level everything to max, again starting from back and balancing elementals out. Advanced units aren't worth the $, except for archers in the Forest level where everything is Flying. Don't pave except to create super-good spots, cuz paving is more expensive (per attack point) than to level stuff to 3+. 1 debuff mage in front of a clutter of men is extremely useful.
