Terribly flawed, but amazing gameplay.
Frustrating as hell. I took a risk and spent my money on the 3rd sword instead of refilling my health and was killed, thinking that, like any good game, you had at least 2 or 3 extra lives in case you die so you don't have to start over and do all the boring shit again. Well, that's not the case here.
The main flaw is the fact that it's difficult to turn around. See, I find the best way to kill a goblin is to jump into the air and slash, that'll make it defenseless, but the thing is, I needed a good distance between me and the goblin to turn around quick enough to jump and slash it. You could make it so one can change directions while in the air, that would greatly improve the gameplay.
Altogether you have good upgrades, this game could be amazing with a little more effort put into it.
