I added promo codes feature to my game - Orbox B: Rebirth.
PC, Linux: progamix.itch.io/orbox-b-rebirth
So if anyone wants to get one let me know in a comment. The code gives - remove ads for free, +2500 coins, +15 crystals. This is worth of 4$ in-app purchase. I'll give away few codes. If more people would comment, I will use randomizer to raffle between.
Also listen to the music in the game. I written it by myself. There are 2 energetic tracks and 2 ambient tracks when playing levels. I think maybe those energetic tracks should be posted to the audio portal on NewGrounds? Or is it worth to post those ambient tracks too?
