Hey this is a really cool idea! Very good twist or "reversed role" for the genre. It was quite charming, and I really loved the names of the attacks!! My second play I ended with a score of 1310.
Probably not in due to jam time limit, but it did feel a little desolate without any sound... but maybe that adds to the being alone and hunter by trainers feeling?!?
Anyways very good job! I could see something like this being expanded upon and becoming a huge hit!
