looks fair
Well what do we have here? a run and jump kind of game? honestly I think its a fair built game with a good kick in its style,such as the cinematic intro and some polygonal 3D on the cave's entrance,and a rather good song to go with it,but I believe it should've been more of a Minecraft/Terraria survival game,but is fully set in an infinite cave where you fight out monsters till your last breath,since we already have similar games like this that only uses less than 5 buttons ,or hell,make the game have this arcadey style into it and have bigger twists than what the game has,like big monsters chasing you,that'd be great.
I have given you a five for the unique style you're trying to make,but I think you should try getting this game to stick out with more enhancements.
