The most frustrating part of Cave Story in a minigame… that was a bit more fun than I expected.
Although, the mechanic of not knowing where I was half of the time, and having to back-track at the price of the chance of losing all my progress, was quite frustrating. If the light went on for a bit longer, it could have been a bit less frustrating. Also, could have used some enemies and checkpoints to make it a bit more engaging and less frustrating, and/or breaking it down to multiple little levels.
I do like myself a little challenge, which I know that’s what the game went for. And it played just fine in that sense.
