Thank you ! I made a faster speed but the playtesters found it too fast so I slowed it so that it would be accessible at first.
The 100 bowling balls shouldn't have happened but I understand how it occured : when you were level 5 (before reaching 100) a ball was already shot, and when you reached level 6 (100 balls) there is a guarantee of 100% spawning 2 balls.
To resolve that I think I'll remove the possibility of lauching 2 balls, and I'll also rework the launch system to shot where the pin is rather than a random value.
Thank you for your comment !!
