Sound works more-or-less ok for me in Linux, but note that I’m playing the downloaded version rather than the applet version. I say “more-or-less” because when I completed the first level it hit what appears to be a bug in Sun’s native code which caused a core dump (meowengine.soundsystem.SoundThread.rawplay() calling into com.sun.media.sound.MixerSourceLine.drain()).
Why should I collect money? Answer: there’s a shop, but I have to go looking for it - I only found it after writing the first draft of this comment. It would be nice to be taken there automatically after viewing my score.
The guns seem to shoot to my side. While that’s realistic, it’s unexpected and makes it easy to miss the first few shots.
The score counter at the end is sloooow. I favour using an S-shaped curve and adjusting so that totalling each individual item doesn’t take more than a fixed, very short, time. 5 seconds on the first thing in the list is too much.
Achievements has 3 'e’s.
When I don’t have a gun it would be nice to be able to punch the idiot who won’t get out of my way. I’m fine with it taking three or even five punches to knock him down.
