nice work, here are my thoughts...
- good graphics, easy to read but would help to have some more detail.
- the gameplay is a bit repatitive
- would help to introduce a store/upgrades early on, maybe after every level
- i wanted to swing my sword faster, and do combos
- the enemies not smart and it became mostly about abusing their ai.
- great death effect!
- i wish i could continue where i left off after i died, just to see everything. then after the player wins, maybe you could have another harder mode where you can't continue.
