This is my retro platformer TheFoolishBrave - To Challenge a God! Feel free to check out the demo on my official site!
Tried the demo - very well done, great animation and amazing parallax background. Very neat and smooth controls as well. Nearly the only comment would be that the sudden non-pixelly font kinda takes you out of it. Also having a halo-like health system in a game like this is a great idea I'd say.
Looking forward to seeing a full version, it's obvious you have put plenty of work into it.
