The tutorial could stand a little extra work. It's not very clear what's going on or what I'm doing. I was wondering how to get additional tech points and stuff
I'm usually not a fan of horror adventures because I scare easy, but you've balanced the creepy quite well so that I was perpetually on edge but without sending me into a mind-blank 'click everything!' panic. Everything was incredibly fluid, indeed I applaud you for including a quick move option from room to room. Each step of the game was taken logically which is an increasingly rare commodity in the genre. At no point did I feel like 'who the hell can play this without a guide?'. I'm glad that I wasn't sent on a (haha) pixel hunt. 5/5 Really looking forward to the second chapter.
I think it should be more clear which classes are activated or not. Coloured are on, B&W off? why not just include a little green tick or something? :S
It's great but some of the things could use adjusting. A lot of the 'bad stuff' is rendered undodgeable in the later stages, especially when you start bouncing off notes and your trajectory is such that it's either you take the hit or fall. Would be nice if you could replenish hearts on the way.
