Hmm that's good to consider. It's funny, for some reason (not on this submission, but on my first one) I did add IJKL as alternate keys as well as WASD, arrow keys, even controller left joystick, and controller dpad as all alternate controls working smoothly all at same time. On my first time making a game too, period, in any engine, never even exported a build or made even a small prototype before that point (which was - I mean, probably just couple weeks ago too. But I also only targeted Desktop too for that jam, since it was.....my first jam and my first time using itch.io too. And that one was a completely different kind of game than the submission I have for this jam).
The submission for this jam however uses a different engine, one that I found much harder to use than the one I used for the first jam (for me at least) but really wanted to try it, for certain.....reasons. This submission just uses simple, basic keyboard controls instead, and it's a totally different kind of game. This is my first jam exporting a web build, period, and my first jam using that specific engine I chose. Somehow I pulled it off (not sure how actually as I was pretty sure I wouldn't have anything, period - for either jam but especially for this one, so I was surprised).
