@nassi yeah I wasn't sure the best way of distributing the game, so I'll bear this in mind for next time (although next time, I think I'll try making something web-based instead so no downloading/installing required)... I do have an exe, so when I'm home I might try uploading that and see if it runs OK on another computer.
I think the problem with the sfx is that when you're shooting, there's only a sound for when you've shot a tomato/banana (since they are useless)... but it didn't quite sound/work the way I would have liked so it is a bit odd. I just realised now that there is a bug with the explosion sfx as well, so yeah... sfx does need fixing.
Hehe, I think I'd rather buff the enemies (or if I had more time, add more variety of enemies that are stronger/weaker). But yeah, it's really as balanced as I would like, lol.
