This game had my brain working more than I expected, great design! I also found the movement, shooting and controls easy to handle, especially for a jam game. My only big problem is the mechanic of switching between different characters that can access different doors has been done a thousand times, luckily the merging mechanic kept it reasonably fresh. The art was nice, and the music was good, especially towards the end. The cliff-hanger at the end caught me off guard! All in all, this was quite an enjoyable game!
