ok before you post anything just know this: i know spelunky xbla is coming out but i think a 2D spelunky remake would be cool! post ideas here and if you want to really make the game and sprites and stuff than go ahead! some starting ideas:
better clearer sprites (not saying old sprites are bad)
new areas (old areas still in game)
new music (old music still in game)
you can make the detailed ideas and later i may jump in and add some of my ideas to!
also greetings from
