how long did it take you to get decently good at the game?

I created this group for players who unlocked the Golden God achievement in Super Meat Boy: http://gtm.steamproxy.vip/groups/smbgoldengods It's a private group, but anyone who has the achievement can join. If you'd like to join, let me or one of the officers know and I'll send you an invite: http://gtm.steamproxy.vip/id/axxxel...

i try to launch SMB but it instantly closes on me, any tips on how to fix it?

I'm trying to get an achievement for completing chapters without dying, but after a while, visual artifacts appear on the levels, and I have to restart the game. Is there any way to fix this?

It literally is not showing ANY custom levels. Is this a temporary issue or what?
