Not bad...
Not bad for a hack-n-slash game, I like how you can essentially buy "level ups"... I focused most of my most on either healing or increasing deadly blow chance, since more money is given for a fatal blow (for some unknown reason). I did notice some problems, however... for starters, at seemingly random times during the game, usually when I was jumping around, the game's speed would increase drastically, maybe 2 or 3 times as fast as it's supposed to play. This made finishing the level rather difficult, as timing arrow blocks and jumps became pixel-perfect moves. I also noticed about maybe 10-15% of the time, when an archer received a fatal blow, he was allowed to stand around until he fired one more arrow, and then he would die. And, with seemingly no way to increase maximum life (unless that's what the 70,000 gold item does, which I didn't come anywhere close to being able to afford), I think the bosses were a little overpowered. Boss 3 took almost half my life with one swing of his sword.
Overall, not a bad game, but the speed problem is quite troublesome and pretty annoying, to be honest. Check out these particular bugs, and you'll have a much more workable game on your hands.
