Very ambitious to try making a realtime combat game in RPGmaker. Got some cool ideas and enemy designs too. However the stretch marks of the engine show in the clunky controls and hit detection. The enemies are too fast, tanky, and numerous to handle at all. I was able to hold my own in Slow mode Easy but that was about it, and the currency gain was too slow to really make me interested in upgrading myself. I can see it working out if balanced for a linear game as you seem to be intending to, and I'm interested to see if you can make it work. Good job!
