The game was simple but felt too grindy.
First level screen clear gave 1K coins.
Second level should have given more for screen clear. Getting 1K for all those clicks not worth it. Stopped playing it after playing second level for a minute
Thanks for the feedback! Did you use the store to buy upgrades? The progression is exponential with those upgrades.
I didn't. I thought it was only collect shells. My bad. Will try again later...
