I would prefer arrow keys too. But the problems was that when I've tried to use them, my computer was counting "ctrl + arrow keys" as standard computer commands for some reason. Also, I was actually using WASD throughout the development, but at the very last moment I decided to change it because I realized that both ctrl and WASD are on the same side of the keyboard. So I just decided to use what was the most comfortable option at the moment (IJKL), but I will definitely change them in the next update
Anyways, I'm really glad to hear that you thought the game was fun. Thanks for leaving a comment and playing the game, I appreciate it :)
