Hi! I tried playing from my pc (no controller available) and got stuck almost immediately - like, take this with a grain of salt because I'm really stupid, but after reading the instruction sign telling me how to fire the gun, I didn't understand how to progress (below the bridge, the way was blocked by the shipwreck, above, by the... bouncy thingies? Neither seemed to be destructible).
The game looks really cute though! Just account for the fact some players are really stupid.
