Thanks for playing!
Yeah, I'm progressively trying to increase the amount of content I make for jam games, I focus so much time on the core mechanics that I always end up having a short time to work on levels.
Regarding the control scheme, after a few game jams I've came to the conclusion that it's very very difficult to please everyone haha. Some people are more used to WASD, others prefer Arrow Keys, some like to jump using W/Up-Arrow, others would rather press space, others would rather use the mouse buttons for that, or even Shift. I've seen some games use mouse as aim before and I went with that because I know most people play jam games with Keyboard & Mouse instead of a controller. I try to appease to a lot of different control preferences, and I usually include basic controller support, but in this case it was scrapped because I was running out of time and my first goal out of this jam was to make something I liked within the alloted time, without having to resort to late submissions. I'm sorry the controls were impossible to you, and I thank you for the candor! (or candidness? english is hard haha)
