Focusing entirely on gameplay feeling and graphic effects seems to pay off, but with that comes expectations with good tunes too. Music was missing for sure, unfortunately! Next time I will look for composers :)
About the balancing of the games mechanics, I did almost none at all, just throw some combinations of enemy waves with no fine tuning. But the general idea is pressuring the player to clear the waves quickly (and precisely) and you can also fire the gun very quickly (at a cost). I may need the cost to shoot higher and the auto-heat lower, but couldnt test enough. Maybe more ground or water level enemies to prevent you staying too much on the water? I dont know.
The balancing act may take longer than making the prototype. And compile times don't help.
Thanks for the feedback! Greatly appreciated! <3
