Pretty neat! Think the concept would've pulled off better if there was a better monster at the end, but considering time restraints and it being your first 3D game, I'd say it's a step in the right direction. So good job and keep at it~
Anytime. And yeah, honestly having dabbled in game development in my spare time, I'm just impressed people are able to make games like these in the short amount of time given. The foundations for a great game are already there, so I'm excited to see what you do in the future.
