Just tested it on an Acer Aspire One.
Runs perfectly smooth, no slowdown at all.
It crashed twice though, before I could get it to run because Zone Alarm popped up - which is my problem, but really it has to be you that provides the solution.
Whenever a DBPro app is minimised or another process takes presedense, it will shed it's media, causing a crash on the next sync. I got around this by adding a check, to see if a known image exists - if I sync and the image is gone, then I load all the media back in again, through a function. This is a chore, but it solves so many possible bugs and issues that it's a no brainer. The chore will actually make your app very robust, you can minimise it, run task manager alongside it, switch to other processes, and your app won't crash. It's vital, and everyone should try and do the same.
One other thing, there might be some performance leftover to hand back and save on processor power. SYNC SLEEP does not work. I suggest adding this line before the main loop:
load dll "Kernel32.dll",1
Then before your sync in the main loop:
call dll 1,"Sleep",wtime
This will pass back wtime cycles to the processor, the more you pass back, the lower the processor usage and better battery usage you'll have. 5 cycles might be a good value. What I did was afforded my game 15 cycles, then anything left over +1 gets passed back with the sleep call, this brought the processor usage down to 30, my game has lots of sprites and 2D stuff, so it's not skimping, and the Netbook is coping very well.
Some feedback on the game itself...
I think it could do very well, it needs to flow right for the touch pad control. I think that you should just move all the players at once, as the ball went out of play and I could'nt figure out how to get it back, felt like I should just be able to move all the players. The other thing is inertia - if you can get it so you spin the players then that would be a very neat control, like slide the player on Y axis, then on the X axis, check the last movement, so when you slide across and lift your finger it spins the players. With that I think it would be very cool, more responsive and natural, keep the ball moving and allow the player to do some cool spin kicks.
I'm not a huge fan of the front end, it's all effective and works, but I think that a simpler 2D menu would be better, the screen on a Netbook is tiny, so it's best I think, to have defined visuals, like borders around text in menus to add definition. Keeping it simple and solid colours, anti-aliased but kinda sharp still, that's the look that I think works best on the Netbook.
Newton seems to run very nicely, all in all it's very smooth and with just a little polish it's something I wouldn't be disapointed in paying a few bucks for.
If you want some more feedback, and netbook testing - feel free to email me new .exe's and I'll test them out.
