First of all, thank you for playing! Secondly, thanks for leaving a review; it's exactly what we need right now. That said, yes, you found most of the bugs we know we need to take care of—like the crow spam, the flawed shooting mechanics, and so on.
The next update will have all these fixes plus new areas to play (currently, there are only three). A tutorial and much more info are needed too; we'll get right on that.
We hope you can play again when it's more polished and keep having fun!
