Well, it's in the title, I launch the game, then Steam say "Nope" and it doesn't launch

Have you tried downloading the game without the steam client? Are you getting an error message?

Does steam show you as playing a game or does the game completely shut down? Can you check if the game ever shows in task manager (assuming you're using windows)

im getting something similar like it the problem is probably the same for you if it shows its running and then nothing happens, its probably msvcr130.dll missing.[EDIT] i found a fix and it works for me now. go download all the microsoft redistributable files and reinstall toribash, and it should work...

Hmm, you can always try that, but that mistake usually shows an error message

Well, for me it looks like this:

It says: "Game launched"
"Synchronization"
And what are those files, where can I download them ? (sorry to ask that, but I'm not English and sometimes it can be hard to understand everything and I'm too scared to fucked up smth when I download stuff :/)
And I've seen nothing in task manager

Tl;dr essaye ceci

Does your other games in steam work without no problem? If so, The problem mostly likely is that some of your Toribash's files are corrupted. I also experienced this problem with one of my games in steam.

Try re-installing the game from steam.

Try opening steam, right click on toribash in your library, select properties, go to local files and click on Verify integrity of game cache.
Does it say you're missing files?

go to the local files and take out these two items
msvcp120.dll msvcr120.dll

dont delete them tho
