I am in complete and utter bewilderment at how you were able to create this in RPG Maker... Not only is that impressive, but the game is also incredibly fun and easy to get into! To start, I really liked the RNG mechanic. At first, I didn't really feel like I would like it, but I ended up finding it very refreshing since it changed the pace of the game. Kept me on my toes and held my attention.
No feedback to give! The only thing, I think I noticed a bug with the boss's health bar; one of the sides was randomly unfilled out. It seemed like it was desynced or something, or just offset from where it should've been. But I mean, it did not detract at all from my enjoyment. Great stuff!
