For some reason, I am spending at least half an hour with this game and I don't really know why... Jokes aside, this is an interesting little game. On the one hand, the game has a lot of places needed improvement, but on the other hand, it's very additive.
Anyway, for some criticism, the stats never progress, and thus changing builds is not really necessary. This is really a shame because it is what this game is actually about (customising swords). The game also feels quite slow due to a lot of button presses required to start a battle, which includes finding a quest to fight (which is 2 clicks per quest), going back and pressing start battle, the is also a slight delay between the hitting animation and actually deducing health, etc. The hurts the pacing quite a bit and I am sure there are ways to mitigate it.
Anyway, this is still a solid entry and as I have said at the very first part of this comment, I am really enjoying myself with this game, so I'd say its a job well done!
