I enjoyed this little Pokemon Ranger type concept. I think the art that you have is really good, I like games set in the sky with a lot of clouds and I enjoyed the work that you did on that front, it reminds me of that section from Chrono Trigger where they're in the sky. I think the game may either be too easy or I can't tell when I'm taking damage, so depending on which it is I would probably recommend to either have the game controllable by keys or an on-screen knob or something instead, or have a clear indicator of what my HP is and when I'm taking damage (some visual and auditory feedback would be nice). Good work on the game!
