The character speed in Alisa's game feels slower to me in the first phase than it was in V1 is what I mean, but that might be me imaging things.
I'd get rid of the 2nd part of the game entirely personally. It's impossible to lose unless you make a super tight timer which would then make the rng ladder room feel super shitty. Personally I think each game should only be about a minute long max given you will have to repeat each game multiple times.
By event difficultly I mean the games themselves generally aren't too difficult. Most the difficultly comes from either randomness (the wave game) or the controls of the game itself as RPGmaker games aren't usually meant for fast reactions.
I love the concept of the game though.
