First off, I think the game looks very solid, and I'm impressed that there is a functional crafting interface and with the amount of mechanics that were implemented. Scene transitions are smooth, and the environments feel visually fleshed out and cohesive.
I found myself in a couple of unwinnable situations - right off the bat, when I first opened the crafting menu after dropping down and collecting the first scrap, the option to craft a health upgrade is blinking green so I thought, oh well I guess I'm supposed to craft that, which locked me out of jumping out of the pit (this was obviously bypassable with the scrap cheat, which I assume will not be in the finished product). I guess since crafting implies player choice in how to allocate resources, what will happen if the player makes the 'wrong' choice and crafts the wrong upgrade? An in-game way to reset at a checkpoint or something might be necessary, because I had to just reload the entire game.
A second situation was in the second room, dropping down into the hidden area - I was unable to jump out.
That being said, the mechanics are there, and it's cool how many things you were able to put into the game. I just worry that the aforementioned hurdles might prevent players from seeing all the things that the game has to offer.
