I really liked the game play for practically an idle game. Just wish your progress could be better shown as the idle game effect you probably aimed for doesn't work if you don't see numbers increasing. Better visualizing the progress would help a lot.

I like the art.

Echoing many of the comments, I think speeding up time would have been ideal.   I think your choice of art assets was great, but I was a little puzzled by your music--it was oddly calming and sweet against the tenor of something called "shoot a bunch."  As well, the explosions were very loud against the music, so a little audio tweaking would have gone a long way.  Best of luck developing on this idea! :)

Neat idea - I think others have already said what I'd say about it :)
The only thing I'd add is that, during the rounds, there's no way to know if you're doing well so even as an idle game it doesn't quite work for me (I like to see some results over time, if you know what I mean?)

Your feedback has been very useful. I have allready added a way for the player to speed up time  and I am currently working on adding some new weapons. Thanks for your feedback and for playing the game.

I liked the art style and sound effects.

I wish you let the player speed up the enemies turn, or do it automatically. Otherwise neat little game

10 seconds per round, with several rounds per turn, results in very long spaces with no gameplay as far as I can tell. I think the flow of the game could be sped up a lot.
