Thanks for the feedback!
I used a plugin in called QInput by Quxios and I believe that those keys are probably just locked by default and I forgot to change it. My original plan for the game was to make a full on Legend of Zelda style ARPG with gun mechanics (using QABS), but I ran out of time and ended up going with the combat system that I threw together on the fly. I guess it's kinda like a rogue-like now.
Frankly this was my first time using RPG Maker and figuring out how to use QABS while also learning the basics of the engine was a bit too much (not to mention I started the game in the last week of the Jam). Anyway, maybe next time lol.
