I am very surprised to hear the game is taking a while for you to load. I have tested the game on 3G cellular and on a raspberry pi; both had the game load within 4-5 seconds.
Yes, I am not an artist personally. I understand the visuals are terrible.
I have got feedback stating controls should be arrow keys or WASD; I will fix this after the jam.
Thank you for your feedback; you have helped me so much! :D
