This was a pretty fun game! I like the fact that the upgrades don't just add benefits, but all have different behaviors for the gameplay, and climbing down with the fish was a real challenge when it strated randomly flipping all of a sudden. Looks like there are some bugs though, for example, you can move outside the screen with the spaceship (to the sides) and easily avoid all obstacles. You don't ven need to do anything, but since there's no list of highscores that doesn't matter I guess. If there was that could easily be abused. Oh, one fun thing would be if all the different upgrades have some form of theme music to go with them, that'd be pretty cool. Keep up the good work!
