This is a really cool concept and you could definitely do a lot to expand on this! I love how it looks too and I was NOT expecting the monsters to do the face thing when I got close to them!!!
(This is the fourth game on the video)
Thanks for the feedback! Will totally expand on this concept and polish the existing mechanics. Unfortunately I only had a week to create this game (animations, meshes, mechanics, lighting, and such). It's the first game that I ever made because I don't have any prior game dev experience. I'll study hard and make more games. Cheers! :)
