This absolutely rocks! I'm really impressed you were able to make all this in just 10 days!
The controls felt real good, and the art looked incredible. I really liked the variety in enemies as well. I kept getting some weird issue though where it would start freaking out after about a minute into each round, and I'd lose control of the game, so I didn't get to see too much after that point. But I think that was probably more something on my end than the actual games fault.
Overall, a really great game! I feel like this could easily become a full fledged game released on steam! Definitely a solid base to continue building off of.
Great job to the both of you!
