To be honest if they tried to imitate IWBTG they did it wrong, since its very different (but yeah, a guy with a gun, I understand what you mean). Im watching it now (0:04:24 mark) and for a first level it seems okay but a bit boring, I really dont expected this game to be long, since it mimic the NES era, but I expect at least to it be fun, I'll give my feedback after watching the video.
edit: Im at 0:14:35 mark and Im already sick about these guys, they are only nitpicking details about gameplay, difficulty and graphics. Also they spit at cool details that are homages to the AVGN series and fanbase showing that they dont even know what they are playing. This game isnt perfect but seems okay until now to me, not even as a AVGN game, but as a game since its hard but not unfair, in fact its pretty forgiving if you remember that they are playing on normal mode and there is a plenty of checkpoints and a energy bar that let you take 3 hits.
They are really offending me, I'll only continue watching because I want to see if they will say something relevant and because a friend suggested that to me (that friend being you, I watch even the shit things when its about something that I like and a friend asks to me, not all the times but you got the message).
When they said that these sprites were Megaman sprite-edits they've shown how much hate they have about this game.
If it was meant to be a joke and they are mimicking AVGN reviews about shit games, but talking about this game, they totally got me.
But one thing I can agree totally: This game doesnt deserve more than 5 bucks.
edit2: 0:44:34, Im starting to enjoy their review, taking them less seriously and ignoring their rants, since Im actually enjoying this game. They are dying a lot of times because they doesnt take enough cara to analyze the situation
edit3: Most random thing about this game until now is Debian logo on sky in the ice level.
