Music was great!  My suggestion would be to turn it down a tad as it overpowered the dialogue at times.  Our game's music was similar to your's btw.  Hope you'll check out our game too!  /jam/cgj/rate/476728

Good entry! I'm sure if it was more developed it would be awesome! There are some little issues I found.

• The game says to press ENTER to start, but the only key that works is SPACE.

• The voice lines were a bit... weird. Sometimes they went well, sometimes it was pure silence for at least 5 seconds, sometimes there would be hiccups in the middle of sentences. They also were a bit long. At least. You can skip them, but going too fast glitched the text box.
• I could see the default Unity skybox in some cracks of the floor (like if they weren't tiled properly)
• Didn't really understood what to do at first. Seems like you simply have to kill everyone.
• The 2 only levels of this game are very similar, just a different weapon but the goal is exactly the same. The enemies' behavior seems the same in both, making it feel a bit repetitive

Apart from that, very decent entry! Congrats on submitting it less than 15 minutes before the deadline!

If you've got some spare time, come try and rate mine! you can find up to 7 endings and a hilarious narrator will guide you!

Absolute cool voice over :D And really cute main character, and crazy enemies, hehe... 

Good job guys with this game :)

Fun! Could be a really cool game once fleshed out.
