Ok,so like...
Idea is good,although it would be awesome to add some things here,and change others.Most likely You wont do those anyway,but I will list few.
What do we lack? - Idea of knight growing in power with each level is easy,but would be cooler to see it like this:Lvl up,You get 5 stat points to distribute,choose what You want.Either that,or some upgrades to equipment.
Skill points and skills are ok.
Balance - as others stated before,bosses are somewhat ridiculous,sure they are strong,and thats ok.But amount of hp they got and exp You get for killing them does not match too well.For guy it takes 3-4 min of evading and slashing,one small raise in exp is just unfair.
Adjustment - I got feeling that for opponents there is no difference where are You pointer at vertical lane,as long as You're near them.What do I mean?
Check out bosses for example,they are preparing to hit me,I rush down below them to other side of bridge,and still got hit,interesting.
That's nearly all....last ting,I passed the game without sweat,while others had problems with opponents,strength difference and so.How?
"Beware of my mighty pause button!!!" - this is interesting bug,it stops time,but not the counter for Your skills recharge.Need Holy Armor often?Np,just pause and wait 30 sec till till recharges.So You can use it right away.Try it,You will know what I mean.
Thats all,don't take that whole bashing personally,I liked Your game and idea alone,but it needs a bit more work to make it great stuff.
It would be really pleasing to see that You upgrade it.Good luck with it man.
