Super Meat Boy (Steam):
Finally unlocked achievement for completing all of world 4 levels ("Hell") without dying after like a week of training and finding the safest routes.
Just today i was so close -- i beat 19 levels in one go and died stupidly on the last, 20th level. Then this night i finally got it but the way it unlocked was strange because achievement appeared when i was only halfway into the world. As it happens -- i don't have to go sequentially and technically can do these levels in the world in any order, as long as i don't die. That might have saved me a LOT of time if i knew that before, because with this trick i could do hardest levels first and then just breeze through easy ones at the end...
Also thanks to
latest speedrun on Games Done Quick i finally beat Dark 4-11 "Surrender" level. I think i stopped playing SMB last year because i just couldn't figure it out.
Spelunky (free version on PC):
I tried it several years ago, but i didn't understand it back then. Now, when i know more how roguelike games are designed to be replayed, i got into it more.
Jumping and running controls are very, very weird at first. They make more sense on controller but even then there will be occasional slip-ups because main character slides like crazy even when you're not running.
So far i unlocked Jungle shortcut and got to Ice Cave several time and that's where i usually fall down into the endless pit.
I wished items made more difference -- for example in Binding of Isaacs items you get into a run create incredible gameplay diversity, but in Spelunky platforming never really changes.
Orbit or Beat (free online flash game):
Rhythm Doctor developer mentioned this game as an example of "actual rhythm game" akin to his own RD or Rhythm Heaven:
http://www.zuzunza.com/myflash/game_detail.html?game_id=562091It's very cool, but i wished it was one button instead of two buttons that you have to press by turns (left/right or up/down). These turns get very, very confusing when rhythm gets faster and especially when changes from offbeat to beat and back again.
