I really liked this, the art was surprisingly good and it was always clear where you had to go next. Every boss had an interesting twist that wasn't frustratingly difficult to work out but did make you panic alot (Looking at you dragon and spider boss xD Thank god for good game design or I might not of pressed z to unstick the sword)
The last boss didn't really have much to it though, I liked the build up to the fight. Found it a little too easy but I knew I was missing two orbs. I read the description and realised it was unfinished D: Aw! I was looking forward to it! Glad you posted it though, I hope you will continue it at some point! (It doesn't seem like there's that much to do xD I haven't used AS2 in ages, no idea what help I would be on that front xD)
