It's hard being a mobile game developer. That's because there are lots of games being released all the time, and because many of those games come from big professional companies.
One tiny indie still living the dream however is Croatia outfit Bit Forest.
Consisting of just three people, they've been working in the spare time on labour of love Comic Battle.
It's an interesting-looking card-collection game that mixes turn-based strategy with RPG mechanics as you level up your squad of characters. There are over 60 skills to experiment with.
Another current trend - see Clash Royale - is that Comic Battle is a PVP game so you're always playing against another player, and battles are short - 3 minutes (see Clash Royale again).
But the thing that makes Comic Battle stand out is the neat comic book art style.
