Started playing It Takes Two recently. The game introduces basic controls, and that's that, no additional tutorials, no hints how to solve puzzles, no characters telling you what to do next when you are "stuck" (many games have these annoying verbal hints when you do nothing for a minute, this one respects its players). It has a lot of places where players can simply play around with mechanics and see what happens, just for the joy of exploration and not some immediate gain.
And it reminded me of playing Spyro back in my childhood days, a feeling I didn't think I'd ever get from any game again. The only downside is that the characters are surprisingly cruel at times, the game's creators certainly lack empathy.
Our experience's different. I'm playing with my husband, and he's generally better at aiming and shooting, while I'm better at platformer aspects, and the characters we ended up playing are sort of wired in the right way for us, haha. Co-op is definitely super enjoyable in this game.
I'll check Tinykin out!
