GREAT!!
i LOVED steambirds, this one is even better
hell i had one hard time on steambirds but the whole upgrade thing AND being able to use different airplanes makes the game a lot better and makes sorta more sense(like having more than just one plane like the first steambirds)
great game, great concept, great play style, also points up for the upgrades and being able to buy new planes
10/10 for all this
well deserved
