I'm looking for games that have a lot of ILs to run. Preferably 2D, but it's not a necessity.

Games that I personally run:

• Inertia - https://www.speedrun.com/Inertia/individual_levels • Sayonara Umihara Kawase - https://www.speedrun.com/sayoumi/individual_levels (2D) • Kishin Douji Zenki: Batoru Raiden - https://www.speedrun.com/kishin_douji_zenki_batoru_raiden/individual_levels (2D) • Boktai: The Sun is in Your Hand - https://www.speedrun.com/tsiiyh/individual_levels • Vanquish - https://www.speedrun.com/vanquish/individual_levels • Squirrel Sphere - https://www.speedrun.com/Squirrel_Sphere/individual_levels

Racing games often have many ILs. One game I run : https://www.speedrun.com/stk/individual_levels

Pretty much the entire Sonic series, ILs are now supported and tracked on SRcom.

While not 3D Airblade for the ps2 has IL select and the leaderboard goes by ingame time. https://www.speedrun.com/AirBlade

Do you like 2d platformers? Both these games have a lot of IL's:

Super Lumi Live: https://www.speedrun.com/Super_Lumi_Live

OCTAHEDRON: https://www.speedrun.com/OCTAHEDRON

Check out The King's Bird on Steam. It's a technically deep and rewarding platformer with a solid art style and tight controls. It has 80+ individual levels (with leaderboards). I started running it a couple weeks ago, I got my first IL record a couple days ago. Shooting for records on all levels. https://www.speedrun.com/The_Kings_Bird

Also check out www.superninjaslash.com. It's yet another technically deep platformer, and one I happen to have the WR for. It's free, and it tracks your time in-client. Technically it has 9 individual levels, but the run is so quick once you learn the route, you'll be aiming for <1 minute completion of the game (all 9 levels). It's still easy and fun to practice one level at a time, though.
