I had a lot of fun with this one, I played to the end! I like how there's a constant sense of progress even if you fail. It was really satisfying maxing out move speed and fire rate. I didn't buy anything health related till the end lol.
You know your game mechanics well :). I had trouble with the level balance, the whole system needs a re-work really, but it was to late for that :). Thanks for playing, I'm glad you made it through! I hope you enjoyed the plot/story side as well. I had a lot of fun on that.
