Neat concept.
Pros: As mentioned, liked the concept. I found the art style pretty cool and unusual. The dialogue was... inspired. I'm glad you don't have to start over if you run out of lives. Otherwise, I would never be able to finish the first level.
Cons: Its quite buggy. The pinkish projectiles dont seem to do anything (don't deal damage). Also the game lags like crazy in the web build on the second level.
Overall, I enjoyed it. Just needs lots of polish.
Keep up the good work!
