I'm sorry to hear that you had issues running the game. I had wanted to have a web version but was running behind and didn't have time to get that sorted out.
I'm glad that you like the visual style of the game, as I felt that was a very important part of this project. As for visual effects, I fully agree with you, and I would have liked to add visual effects and potentially attack animations to combat, but ultimately decided that it would have to wait as I didn't feel I had enough time to add it in.
