yeah, because RPG Maker is japanese software. and japanese games often have Z and X without configurable keybinding as well. really frustrating when i wanna play japanese games... especially plattformers... i suffered a lot from that... had to set an additional keyboard layout (QWERTY) in my system (language settings u can add additional keyboard languages) to switch to for those games... but always annoying when i accidentally switch (default shortkey for switching layouts is ALT + SHIFT easy to accidentally trigger when doing another shortkey with those 2) or forget to switch back and then try to write something and z and y r always wrong and all special characters too... so whenever possible i change the keybind ingame instead. and if its possible to send feedback to the dev(s) i always ask for keybind configuration.
