good game the art is awesome and the sound is fun i like it, 4 notes though
1. add more bars/feed back, bars for waves and reload time and bullets i need more info
2. collisions were a little buggy like when an enemy dies for a short time there collision was still there making an invisible wall, or the bullets would go over spiders witch was annoying cuz i cant control up and down aiming and it was a little confusing at first cuz i was aiming in the same spot and the spider wouldn't move but it would randomly not hit the spider or the sword would curve up and go over enemies looking like it should hit them but it didn't
3. make some way i can see the enemies behind walls cuz there was one time there was an enemy hiding behind walls and i couldn't see it for the longest time and it was the last enemy, or a web was behind walls and i got stuck with out knowing where it was
4. make things more obvious like the webs (like adding a contrast out like to it or something) this kind of goes with feed back
All in all good game i could tell that you had fun making it and that's all that maters!
