Jump 'n Bump 2 (with cats)
Level designs aren't astonishing but still, it's fun hardcore platformer which reminded me Jump 'n Bump and Super Meat Boy with cooperative mode(s). But it has also some flavor from "Jinsei Owata Daibouken" and "Shobon no Akushon" in some levels.
Art style is good and reminded me 90's cartoons. Game itself represent a DOS game with clean visuals. Blood effects are awesome. Tracker musics are great, my favourites are menu music, first level and castle themes.
I read the negative comments about online problems but it seems like online play a little bit fixed since last year but it still has some problems like connection timeouts or connection fail errors (i don't know if it is my dormitory internet or not though). There are enough amount of players and rooms but mostly they are private and they don't play Race or Deathmatch but Adventure mode; i don't know why. Hotseat (local) play is always available.
Cooperative adventure mode is a little bit chaotic. You accidentally (or purposedly?) bump and kill your partner and/or prevent them to reach their goal or they do the same to you. Also they distract you because, you know, there is something moving over there or something funny happens. Time by time you or your partners activate a trap and you can't handle the timing of it and die. But these kind of incidents make the game more funnier.
There is also a level editor named Aftershock but there are no guides about it and it's not so user friendly. You can find custom levels to play on Steam Workshop. Just hit the green subscribe button.
I bought it for 2 bucks and i can recommend it to you if you like hardcore platformers.
