Just finished the demo and it was really fun, the combat was solid and the pulse system is very refreshing, however there are some problems that I faced when playing the game.
- The first problem was that the poles that the player could grab onto easily blended with the background and were hard to see (I spent 2 minutes walking in the area above the green door wondering how to get up the ledge before realizing that there were poles), I would recommend adding some torches or glowing things at the ends of the poles to draw the player's attention to it while using the old pole sprites for hidden areas and secrets.
(If you play Devil May Cry 4/5 you will see that Nero's latch-able areas always have a blue/cyan glow or fire around it)
- The second problem was that the area where you climb up a broken wood stairs was VERY confusing, mostly because I easily mistook the foreground for platforms, it also happened in other areas but this specific area really made me frustrated, I would recommend making some different shades for the foreground and background so that they don't get confused with the platforms and walk-able areas (or it might just be me being stupid :P ).
- The third problem was that the enemy health bars easily blended in with the colors of the sky that it became hard to notice, I know that visual consistency is important but sometimes the colors are TOO consistent that it all blends in and becomes hard to notice.
Overall it was a really fun and refreshing game with amazing visuals but it suffered from lack of visual "depth" (idk what the correct word is but it feels like the world is flat without much distance between the foreground and background).
Good luck and hopefully it keeps getting better and better.
