I really enjoyed this one. It has a nice progression to it, gaining new abilities and re-speccing your dragon for the challenges ahead. The controls were simple and intuitive. The system of distributing your points between the different sliders was cool, added an optimisation aspect to the game. Although it felt like there was really only ever one optimal layout that didn't change much throughout the game. With some more balancing I could see the game really encouraging the player to tune the dragon's settings to the specific kinds of obstacles ahead. Also the dialogue sections do stretch out a bit, I think allowing dialogue to be skipped through quicker and removing extraneous lines like "Cool!" woud help a lot.
Great work! :)
