I explored a bit, I liked the music and I liked the change when you went underwater (did you just turn off tracks underwater?). Def looks like you ran out of time in terms of adding game loop etc. but it's a cool voxel engine and interesting objects - flowers on the path that shake when you touch them etc. Was hoping you could interact with the fishing rod (and fish!). Game sometimes hung which was distracting (AMD 9800x w/ Nvidia 5700).
As someone who used to do game dev stuff before engines were available it can be fun/challenging/interesting to build stuff from scratch, but I always got stuck working on the engine and did a poor job prioritizing game loop stuff myself. Either way cool stuff!
