What a funny game!
Visual
The game looks cool, even though the snow looks a little weird when you dig it, but that's not a big issue. The winning screen is very low resolution though :(
Audio
I love all the audio of the game. You even got me dancing on the winning screen!
Tutorial
Unfortunately not much in game, but you thought of showing "press E to pickup", so big up for that!
Maybe say in the readme.txt that you need to use mouse wheel to switch between shovel and detector. Took me time to realize that.
Gameplay
- The idea of detecting items using sound is pretty nice, I always like game that include this little but easy trick. And I'm always really bad.
- Trying to find the gifts when digging is fun too :)
Fun
The game is fun! I really liked searching for gifts and trying to guess what was in each box. Spoiler: I guessed nothing. Had pretty funny items too :)
Bugs
I didn't encounter any bugs, so that's a great point for me :)
Theme
Completely in the theme :) Good job!
