Hi, maybe you know a game on the web that is also a classic platformer I mean a platformer game with platforms, spikes, and the player can go and jump without extra stuff and also in 2D

What do you mean by "without extra stuff"? Do you mean you want no additional mechanic besides the vanilla jump at all? Such as wall jumping, double jumping, attacking/dealing with enemies, etc.

Or do you mean you want straightforward levels with no puzzles or mazes?

Sounds like a bot

Not that is not true it seems to you perhaps because my English is not such a great

@TuttereyTutterey He has plenty of runs.

@HaimHaim I can't think of many (non-meme) games where you have nothing but a plain jump and there are no enemies. Maybe check out Match Girl and Start Powerless and see if they qualify?

I can think of some where there's just one extra mechanic, such as O-Well (ledge grabbing), or where there's puzzles & enemies but just a normal jump, such as Red Beard.

I've got one just like that @HaimHaim
