Pretty nice game! I had some screen stuttering issues, it would freeze for a second and continue playing afterwards. The box colliders might be too big for the fish that we have to avoid because they get triggered even if we're not touching the object, as in the sub is close but not that close that it would warrant a collision being triggered.

Great job! A very colourful and fun side scroller. Quite a challenge. But I did manage to score 2073...not sure if that's good though? Ha...it would be great to hear some sound effects and/or music but you've got the makings of a super fun game. Great job!

Nice gameplay, and nice implementation of the UI and points system. Keep up the good work!
