Thank You for playing! Yeah it is a bit easy for now, increasing the difficulty a bit might increase the gameplay time XD
And about the Enter button part, though I did consider the switching of hands, personally I have been using my laptop for developing this game, and since I use the touchpad and arrow keys, it was not much of switching hands for me hehe. Thanks for pointing this out, I will keep this in mind in future posts, and if possible, can you suggest me any idea of which button would you have preferred for the particular arrangement you follow?
And as for the tutorial part, I will definitely look into putting a prompt to start the gameplay in a future update. The game mechanics and the snake AI took quite some time due to which these I missed out on some of these intricate polishing. Once again, Thank You very much for your feedbacks! :)))
