Addictive.
It was a great and very unique game, but there are some problems.
1) The save system is really strange for me it auto saves after each battle even if i lost - so the save game button has no use whatsoever because i cant use it to reload after defeat.
2) battles have a very random difficulty and it somewhat depends of what weapons you would be getting from this battle - e.g first middle weight match is harder than the second one and i even couldnt beat 9th because these laser thingys owned me every time and well i got tired after 10th defeat.
