very good, solid 9 and here`s why:
very good artstyle
functional and responsive buttons and so on
a tile based game, which are my favourite,
it gives the vibe of games like kingdoms and castles and so on
good audio
the idea is nice,
smooth transitions in like, the game itself or the button,
good idea,
one feedback:
flood level 4 is soooo op, I didnt survive it at all, and I like was too dissapointed to like try to recover, (noting that I played it again, in other words, I spent 1 hour literaly playing your game, and am gonna return to it, loved it, and you, have a good day)
