Thanks for the feedback! The health bar seems to be a common complaint - noted! I would have liked to polish the transition a bit but in jam tradition I ran out of time. There was a lot I realized I just didn't know how to do and didn't feel like I had the time to learn properly. I'll have to spend the time between now and the next jam I join working on those.
I can totally relate to all of that--especially since learning while coding is why I couldn't finish. I would have the same issue with transition since the elegant and obvious way to do it would involve a shader, which is not something I have a lot of knowledge of. I would use this method here in a pinch(tutorial is in french, but easy to follow) for a quick and simple transition.
