Thanks for the Feedback. Yeah i ackknowledged that already as a problem that not all coins are visibile, some are behind the plants. i like the idea with the particle system to emit some glitter or something. Will probably implement something like that or a nother method to make them more visibile, or at least a visible area around the player when he is behind objects so that you can the those areas.
I hope that the next build also fixed the issues with some of the coins slipping through the terrain.
