Great game, but maybe add in something like a fishing boat, that can be set to go out and get either money or EXP for you every hour automatically, or something along the lines of auto fishing just to add a bit more of an "idle" idealism to your idle game
I know this is stupid, but the infinite fish bucket scares me, maybe you could show one of each type of fish you caught sticking out of the basket? just so I'm not afraid to fall in?
this is a great game, but there needs to be a way for me to go back and replay old levels. when I buy a new ship, I don't want to take it into a battle it can't win. also, the level cap systeme seems to be useless, seing as I am still killing unts of the same level, just for less xp. the game is good, but with a few minor changes it could be great.
as you can see, it is in the penguins nature to randomly combust when they lack food. also, they cannot see objects, only food in the form of turtles, so they will run at an object until combustion thinking there is nothing impeding thier paths
