I really love the game and I am thinking about running it, the only game I tried to tun so far was portal but I didn't really have much fun with it I was thinking either I will run Battleblock or hitman Blood money. How hard is this game to learn?

Hey, so I have been doing runs of portal (Inbounds Legacy) for a while now but I didn´t really enjoy it. also I could never record them because I am playing on a pretty old Laptop. Do you have any suggestions for other games I could run? I personally enjoy playing games (casually) Like Iconoclasts, Celeste, Flinthook, Basically any roguelike/lite, Tf2, other fps games Portal. I know a lot of these games have a pretty nice speedrun community but for starting out, they just seem a little bit hard to pick up. also I need something that runs on my Laptop well. my specs are:

Intel Celeron (2x 2.16 Ghz,) 8Gb Ram Intel Hd integrated grafics x64 Windows 10

Games that would run well on emulators would also work but Please let me know which emulator I should Use since I know that not all emulators are allowed for all games.
