Spelunky gives the player everything needed to succeed from the start so it is only when the players skills get better will they advance.

Being that Spelunky is at its heart a roguelike the gameplay sessions can tend to be quick as the player will die quite often. This makes for something that can be played in quick bursts throughout the day. the convenient saving also lends to this as a game that is still ongoing can be quickly saved in order to be picked up at a later time.

Ranging from Mega Man to Metroid, there are a tone of great mods for Spelunky all of which make for a new experience in the game which vastly expands the replayability.
