I loved this game. It's fun to play and i've never seen any game mechanics like this. just the last level that gets a little boring with all the upragrades, making the endless part obsolete (I didn't play it). But still, it's one of my favorite game, even if i'm a fps player...
oh, can you please share the soudtrack on deezer, or another platform? it'll be in my playlist as soon as I can!
(and sorry for the bad english, I'm french...)
