Since you want to play one game per day for a year; I assume you want relatively short games or categories, that don't need much time to get into.
- Web games are good for that, because you can start speedrunning a web game immediately without any preparation, and most of them are short (up to 5-10 minutes). So you can search the games list for web games and see if you like something. (You can sort by player activity)
- If you like or want to try short 2D platformer web games, here are some suggestions:
- Everything in the Eddynardo series: Sleepy Knight, One Trick Mage, Choppy Orc, Sticky Sorcerer, Greedy Mimic, Hasty Shaman
- Games by NoaDev: Fireblob, Emerald and Amber, Gum Adventures DX, Mini Arrows, Mini Blocks, Mini Colors, Mini Dash, Mini Jumps, Mini Push, Mini Switcher
- A Pirate and his Crates
- Hat Wizard 1, Hat Wizard 2, Hat Wizard Christmas
- Celeste Classic, Celeste Classic 2
- Every Pico-8 game on the web-games list, their icon looks like a sort of cartridge
And of course: This masterpiece

"Platformer Game" Series:
please speedrun https://www.speedrun.com/franklin_the_turtles_balloons_away it is a good game and definitely totally isn't 95% rng you can get a 21 and have tied wr pretty easily unless you're like me are willing to grind for sub 21 which is probably almost impossible but i am doing it anyway and no i am Not okay.
Now that I sent you a few short meme games that I wouldn't run in a thousand years, here's some actually decent webgames, from the Karoshi Suicide Salaryman series:
Going to share some short games, some of which I mod and/or ran before:
https://www.speedrun.com/disneys_party_gba Basically, Any% involves selecting the 1 Day option so that you only play one board, wasting 12 turns as fast as possible, and then fighting the final boss. You can hold start(?) to speed through dialogue and hold A to speed up the dice. You could also run any IL. They're very short, but you have to unlock them but successfully completing an attraction (mini-game) in party mode (you have to land on a space to play the mini-game). Emulators are allowed. mGBA & BizHawk are recommended. Should probably take around 10 minutes if you've never played before.
https://www.speedrun.com/gmd Many short categories to choose from:
- 5 Rated Levels: Shortest category in the game. Beat any five star-rated user levels. Recommended levels are Stageix, BdoubleO, Weightlessness, Geass, & Demons. They may take some practice, but each level is less than 30 seconds.
- 1-8, Any%: The classic. Most players can successfully do deathless runs of this. Playing the free version of the game is allowed for this category.
- Gauntlets: Basically, these are sets of 5 levels. Each is less than 10 minutes deathless.
- Moving Obstacles II: This is found in ILs. You basically control both the cube and the stage and race for an in-game time.
https://www.speedrun.com/geometry_dash_meltdown https://www.speedrun.com/geometry_dash_subzero https://www.speedrun.com/geometry_dash_world First two are less than 5 minutes, last one is 6 minutes long. Turn on airplane mode to disable ads.
https://www.speedrun.com/rtue#Old_Revenge Set of short Undertale fangames. Old Revenge & Disbelief are the easiest categories (from my experience), with Disbelief (Spare), being the shortest. All are about 3 minutes, Spare is less than 1.5.
https://www.speedrun.com/ccf Basically Minecraft Classic.
https://www.speedrun.com/titol Every game from this series is short enough. Not sure how to get some of them working because of Flash player being taken down, but you can join the Discord and ask for help.
https://www.speedrun.com/labyrinth_2/full_game Lite Levels is the shortest category, featuring X level packs, and is played on the free version of the game. If you can find an APK of the full Android version of the game, you can jump straight into Kindergarten, the shortest level pack of the game (20 seconds).
https://www.speedrun.com/the_cube APKs of the mobile version exist. The game is really short, but it's so so so so so bad. Please take my word for it.
https://www.speedrun.com/dt I'd be a fool to not recommend this classic. A little bit of practice and you can complete this in under 10 minutes.
https://www.speedrun.com/disneys_party Minigame Mode: Win one minigame. lol
https://www.speedrun.com/marioparty9 Time Attack should take about 10 minutes.
https://www.speedrun.com/sik I guess all of these are short. I only played Space Is Key Hell. They're all webgames though.
I feel like there's more I can add. Might update this later. Sorry if this list is a little too long. XP
