Hey 6knowledge, thank you for trying my game!
A feature the game is currently lacking, that I really wanted to put into the final game, is the concept of combos -- ideally the player would have a list of sushi items (much like a menu at a restaurant) with indications on which pieces of sushi to stack to make more points (alas, it didn't make the cut!)
I do agree the game starts fast, and only after some retries it becomes a little clearer: a tutorial wouldn't definitely hurt.
Thanks for the suggestion, have a great day!
