We plan to add more to the dragon later (following you around, fighting, fueling structures, even flying on them)... but they are useless in the current version - sorry!
The player should have more control over the results of training, for example waiting 20 seconds for a star to fall is simply boring and doesn't feel challenging at all.
Yeah I kinda agree. I'm reworking some part of that, like in the sequel's Strength training, perfect are now based on timing (more like a Rhythm game).
