It's alright. The second level was kind of tedious with having to look behind you shoot a bit, then too the front. And accidentally killing one of them is annoying. Other than that it's neat. A retry button would be good.
I know what you mean. We wanted to explore all possible ways to interact with the new mechanic, the second level is more towards a puzzle game and can be a bit annoying (it actually was way worse during most of the development ;-) ). Could use some refinement for sure.
