Since last version, from last year, we've been working on a lot of updates which include the following:

- Three and four player battles
- New characters and stages
- Character stats (speed, weight, weapon and bomb)
- Destroyable levels
- Bouncing level tiles (when hit from below)
- Instant kill bullets
- Play ends after 5 rounds and shows a ending screen with statistics
- Keyboard and joystick can now be redefined
- Completely redone and/or re-factored a lot of classes and code

It's available for download here:

The next thing we will be working on is a single player, which include some missions. This is still in planning phase, but we've got some really nice ideas about what we are going to do with it.

Stay tuned!
