Hi koomaluola!
Welcome to PGD forums.
I'm sure you can find some pepole prepared to test your game but I can not guarantee for them to be active testers. You see most pepole here are also developing their own games or game engines so many of us don't have much time for playing games. But still we will hep out a felow pascal developer as much as we can.

Please spent some time browsing through the forum so autopromotion system can unmoderate you so you will be able to post anywhere on the forum.
After you have been unmodreated I suggest to create a new thread about your game in "Your Projects" section of the forum. This way you would atract more pepole.
