Hi,
I've tried your game/simulator and It looks nice
Just some indication from a biathlon fan:
It is nice that the race are nearly 10 minutes long, but the time showed must be neraly 30 min in a mass start
I don't know of you already do it, but shooting times and percentage must be different between prone and standing
In the menu mass start is indicated 20 Km but in reality it is 15 Km for the men and 12,5 km for the women
Maybe you have to take in consideration that some athletes are stronger than others in the last lap
Also there are different shooting percentage for the same athlete in the relays that in the individual races
As other people says the penalty loop need to be longer
At the end of the day, your project is very promising and I wish It will became one of the best winter sports simulator ever made
Here is a good site for finding accurate stats on biathlon

Thank you for the game, when it will be at version 1.0 I'm sure I'll make a donation
