I thought the gameplay was pretty fun
the design of the level and enemies blended well together creating a hierarchy between dodging and attack that I found to be enjoyable.
the scripted events such as falling down into the second part of the level could use some tuning but it doesn't affect gameplay.
I only have one real negative and it has to do with the game maker installation client. Maybe just upload a copy of the executable for the game itself instead of the install client. I almost didn't play this because it required admin permission and it made me think that the file you uploaded was suspicious.
anyway, I liked the game and would love to see it fleshed out in the future.
