You had me with the presentation but that level 2 boss is a showstopper.

If you're good at tough puzzles and tough platformers, and actually have a local friend who's in the same boat -- this is the unicorn of a game for you! This is the most rewarding coop experience I've had in a very long time. The puzzles are innovative and organically put players into different roles -- one player navigates passageways in the dark while another controls a lightswitch, one player collects keys while the other kills monsters in their way. The boss fights are on another level, requiring tight timing and puzzle solving, both in figuring out the boss's weakness and exploiting their patterns -- "The boss always chases you first, so try to lure them to the other side so I can get this box without being hit by their fire attack." Now the downside -- this game is equal parts tough puzzles AND tough platforming. When playing coop with a friend, it can be frustrating or embarrassing if you or your friend are bad at pushing buttons. Some levels really just come down to letting them try it for 15 minutes and then having them sheepishly hand over the controller because they can't press buttons fast enough. And unfortunately if you have a friend like that, you will probably just get stuck at one of the boss levels where you both really need to be on your A-game. The single player experience is also great -- the puzzles and bosses are all completely different and significantly easier than their coop counterparts. But, it is still a fun challenge. Really though -- definitely top 5 coop Steam games of all time for me, just a phenomenal package and stellar level design!

it's pretty cool

Hard as f*ck, but one of the best co-op ever

This game is severely underrated. It's challenging but in a fun way, looks amazing, sounds incredible, and plays nicely (especially with a 7800+ controller). Highly recommended!

Pretty fun game with a great visual style but only really shines as a co-op game

This is a neat game, but after the first world it gets really frustrating honestly. The difficulty jumps out of nowhere, and the second world's gimmick is just annoying. This gets extremely bad at the second boss, which is invisible most of the time, but also moves seemingly randomly. Because of this you can just get hit and have to restart. It luckily gives you an infinite lives mode but even with that I just found it annoying. It's a shame because I think the game is fun at its core, but I just don't have the patience to continue after beating world 2.

Pretty impressive for a Atari 7800 game.
