The ending of the level with Walter's wife actually made me tear up a bit. This game hit really close to home with the feels.
The art style was very nice although the level design itself felt rough and moving objects felt very unfair at times. Collisions were kind of janky, especially with trampolines. I can get over all of the jank (even if I wanted to pull my hair out at times) with the storytelling in this and putting a kind of "reversal" on the theme was absolutely genius. Definitely going to play the updated version when I can.
quick edit: not sure if this was fixed in the updated version but I think if the grapple mechanic wasn't done it shouldn't have been accessible at all - it is very easy to break the game and clip out of bounds since it is still there.
