its $15 thats around R120

i think this game has what it takes to be around a long time ... it has the aspect of tower defense where you stop the creeps from getting to the crystal and it has the RPG going for it, so that's 4 heroes with at least 3 different type of builds for each of the heroes ...

the difficulty level is really something as well, because you finish a level on hard and it was a walk in the park dont thing that the next difficulty level will be slightly harder ... the challenges which is like a different mode are quite intense as well

and for future expanding of the game there are talks of 2 or 3 more heroes, they also include different events on an occasional basis like Halloween ...

oh there is also so PvP as well as 16 man CTF PvP

i think the only gripe i have with the game is that they released it at the wrong time ... you dont release your indie game within a month or two of BF3, MW3, forza 4, uncharted 3, gears of war 3 or any other awaited title that has cause so much hype.
