Nice start to a game! Good controls, good graphics, etc. Some things I would say:
1. Hit boxes seem a little off, MOBs are hard to hit until you figure that out. Skeletons especially.
2. When jumping or falling, the camera needs to show more of what is below, so I can plan my landing.
3. Landing on spikes throw you forward, so it is possible to get trapped between spikes and a wall and there is no way out.
