Visuals and gameplay are extremely polished for such a short development time :O Good job on that.
I only had one problem.
I've played until I beat the >1000 level and that's where I stopped.
The game is really good and I would go further but I would really like to have a fast forward / skip button because waiting for the really long scenes to finish is tiring. I had: +2 x2 UFO UFO UFO ... setup for the >1000 scene and I thought it's never gonna end :D
If you add this feature I think this can be a perfect little puzzle game :)
