I work as a solo developer on a full scale multiplayer project for 8 months now, using only Blueprints. I really love programming with GUI and I kind of want to show other devs, that they should not be afraid to use BPs.
I also do all the 2d & 3d art by myself.
Tidewoken will be a turn based PVP game, with a combat system like Dofus or FF Tactics. I already implemented stuff like Dijkstra-algorithms and line of sight checks, large dynamic spell systems, buff systems, turn systems, tile based movement system and much more in Blueprint.
