Nice game! I loved the low-poly style, short game and quite fun! nice idea, I think the camera was a bit hard to control, it was inverted which felt weird, I liked ur water shader though!
Maybe u can expand the game and make it a platformer since u have a jump button which felt useless, also I think u should invert the walking and running, currently u use shift to slow down but I think the opposite should happen (up to u ofc)
Game lacked any audio but I think its fine since the game was short! but a nice background song would've been nice :D
