It's fairly neat and feels like a good amount of thought has gone into it. But wouldn't this be better in the WIP forum?
Anyways, I downloaded it and gave it a shot. It starts fine but once I hit the 19seconds gameplay time, it slows down to a crawl. Something like 0.5 fps. I'm using Windows 7 with 8GB RAM. It's probly using the Intel graphics chipset and not nvidia, but that shouldn't really slow it down so much.
PS: Nice to see you're using slick. I've just recently started working with it.
I wanted to put this here, because it is kind of a finished prototype. We are not currently coding this anymore, but we might return to the subject in the future, and it's good to know if this doesn't work on some machines and so on.
That slowdown sounds strange, I should test the game more. I don't recall hearing about those problems before, but I made some changes before putting this here so maybe I broke something.
Slick is a good and simple to use library for these kinds of projects. I'm sure you will not have any problems with it.
Thanks for the feedback!
