My feats didn't save, and it'd be nice to put in a save feature anyway.
Plus, the graphics are a very bland and the scoring system isn't explained. A good effort.
Don't know if this is really much of a bug or not, but if you jump straight up and hold down, you'll slide forward when you hit the ground (even if you had no horizontal momentum).
Why does the strength change so much when I haven't touched the mouse between shots? There should also be a "previous angle" option which would make playing a lot more fun. Add in a mute button and you have a game that might be fun for a less strategic clone of Worms.
Really, really cool...the only problem is I have a bad connection :P
Even still, I'd give it 5/5 just because you can upload your own songs. Tons of fun.
