Simplicity: Really simple, mechanically, visually, and storywise. Maybe less simple to someone without much experience with older games.
Fun: Not the most fun, but I don't really like this input for shooters. I didn't rate you too harshly for it, because that is my preference.
Creativity: Not too creative a core concept, but the setting and art was creative.
Visuals: Very few 3d games in a jam, and you made it look very impressive. I love it!
Sound: Not too noticeable. I didn't knock you for it or bump you. The audio transitions are rather jarring, however.
On Topic: Not the most on topic, but better than other games I've seen.
It's a shame this game hasn't gotten more rating. I've found that rating other people's game is a great way to get feedback, so if you want feedback, try that.
