Thanks for playing! Ahh, thanks for your comment about the mouse vs keyboard (I'm working through a few comments at the moment that only had minor input issues). That makes a lot of sense why we never caught that issue, we were both testing gamepad, keyboard and mobile touchscreen (and not mouse) as the inputs, as the mouse was never intended as a main control (however we /did/ let the player use one, so that's on us for not testing that method fully).
Also, thank-you for you kind words on the art! Yes it was fully created by me, during the jam. I think I spent way too long on each asset, as this was my first time making pixel art assets from scratch (I'm normally doing 3D or 2D vector), but I'm pretty happy(relieved) with how they turned out in the end.
