Got reunited! This was great.
The game has plenty of content, and I like that each level after the tutorial makes you use the two characters a bit in a different way, from a straight duality puzzle to simply switching between each one for their weapon in the last level. I get the level increasing length order but I almost feel the order could be inverted so that the last level is the one where you need to pay attention about using the two characters in the same time the most so they don't die.
Not sure I ever played something similar in first person. The levels are pretty good with the right difficulty for the context.I got to die quite a bit, it was fun to apprehend and solve.
Good job, I greatly enjoyed my time with the game.
