(I am now in a rush to test as many games as possible to help, so please do not mind the cursory reviewing style.)
Semi-on-the-fly remarks:
menu: the dog selectors have some positioning trouble
advise people to play on full screen, otherwise, things get out of the screen
controls ARE layout-independent!! :D (I have an AZERTY keyboard)
top-down shooter but sending love instead of damage! XD
Nothing happens at the building; ah, I see in your answer to SpicyFrog that the game is unfinished. You should state it on the game page, so the players do not get confused and try continuing.
Takeaway: as I said above, top-down shooter, but sending love instead of damage. Super sweet, although I wonder if you had other original mechanics in store once we have our new friends… A bit hard to judge, as it is unfinished, but the sweetness is here. :)
