Woah, 10mins? that all?
well it was probably less actually. You do know can play 10 levels from each difficulty type in the demo?
No I didn't, this certainly may increase time spent playing the demo. Perhaps this needs to be clearer somehow on the selection screen. Also after doing 10 why not say, now try the others, or if you said that already, make it clearer!Yeah I heard the trumpet sound, but didn't associate it with anything, then later on I thought oh it's a low pushes warning and goes off at 1 push left (which doesn't seem to be true according to you). So the point is I wasn't being super observant but neither will you customers be, so there may be room for improvement. Trumpets aren't enough.
Ah one more thing before I forget, when the bubles pop, you are simply playing the pop noise in mutiple channels (I think) and this builds up to a super loud pop that distorts. Perhaps you shoudl consider a) having only one pop i.e. restarting the sample, or maybe just two channels b) when you start a new sample, drop the volume on any playing samples so that the overal volume is still the same. This is a common technique in pro games. I ran into similar problems with Xmas Bonus. When too many things popped at once it was really loud, so I had to try out a number of techniques. Just an idea :-)
