Ok, now that i have finished the game i guess i will give feedback... Great game!! Even though it would seem to have low playability, it is actually fun to play for an extensive amount of time and it doesn't seem to get too boring unless maybe you went to level 40+. Yes we have all seen TD games, but this here is an example of an Excellent TD Game. Also i really like the strategic game play, especially with the specific land, and the forests. 5/5 (or for unofficial scoring...10/5 :P) The one problem perhaps is that the game could do with more levels and/or game-modes like a challenges section...(challenges such as only having one gem, only one enemy, no spells, specific towers, endless mode or even a mode where the gems are extremely easy to get (where you would have to fend them off...and possibly only having complete of incomplete instead of brilliant etc.). Again Great game...keep up the Awesome work!! =)
For the 'Tukkun FCG'
There should be opponents that only focus on certain elements...eg: a fire only enemy (or at least heavily influenced by the element)
Tukkun, i think the lolmarket is glitched...
i bough red gems when they were at the minimum price (250), they're still 250 (thats not the problem though), and it says profit: -153!!
Just 2 suggestions for the battle arena, you could make them detours or something...
