not bad but there is room for improvemnet
I lode the consistency of the art style, it all looks quite professional. but still the first LVs piglets and chickens for enemies? the little piggies look so darn cute it hurt me every time I had to put them down.
now when it comes to game-play mechanics: jumping was pretty much redundant but still there were times during the boss's fights I wished I could jump in any direction not just back and front.
also the enemies became challenging only when they amassed numbers, they should do a better job trying to kill you and protecting themselves, dont know maybe allow most enemies to jump back in anticipation to your attacks or even allow them to block some of your attacks, just try to make them more efficient fighters because most of the time they only dance around you waiting for you to kill them.
in the sound department it is a shame there was only one musical score, it was a good one though. also and very important Jun sound likes a dude you should address that problem as soon as possible.
over all I find it to be an enjoyable game with lot of potential to be more than it is now.
