DelugeRPG is an online game where you can catch pokemon, trade them and even battle them against other players. The game was initially based on a lot of features from PokemonCrater.com, but has expanded a lot since then.
For development, I've used gedit, Geany and Atom text editors for all the coding. GIMP was used for any image-editing. The maps currently being used were made with Tiled. Sprite variants are made with Phatch. We use GitLab for code management.
