This was a really fun game! I got all the way to level 24 and got a score of 720! I love how the diffculty slowly ramped up the more powerful you got! That was really good game design and it felt very polished! And the sounds were really well made, it didn't sound annoying to hear the death sound over and over again, or the shooting, so you know some thought went into their design/implementation!
Keep up the awesome work!
