Really fun!!! Only thing I would add is that if u have 1 item remaining, you can continually press on the single item and crush all the crabs that way. Overall amazing entry!
Very casual game. I like the hand-drawn textures a lot ( the crabs look quite cute!). One thing I'd add is having the button go a different colour (like green) when the correct amount of coins has been accumulated, so the player can be aware of when to upgrade, other than that, however, good entry!
