If you increase the credit gain by 50% it goes up to 360 credits. Now if you do the math every hour you can only 2 cores which bets you 720 credits per hour, but this makes no sense since currently you can do 3 cores per hour earning 240 credits per escape which per hour amounts to the same lmao. So in reality if you increase the time at least make it so we get 500 credits per boat escape
As an additional comment, the map expansions are increasing overall escape timers and the escape difficulty as well (especially for the boat escape), so making it less frequent with better rewards makes more sense.
Also, the reward for the object hunt competition should be doubled or tripled.
