Super Meat Boy (Original) & The End is Nigh

I recently saw Super Meat Boy 3D come out, and it sparked a big chat with my sister-in-law about hardcore platformers. She's a huge fan of Super Meat Boy but never got around to playing Celeste so I recommended that.

I first played Super Meat Boy on the Xbox, so I was really itching to play it again. Since it was only £2.99 on the e-shop, it was a no-brainer. I didn't even know about The End is Nigh, which is like a spiritual successor to Super Meat Boy, but I grabbed that too. I totally forgot how easy and fun these kinds of games are to just jump into, and how perfect they are for playing between bigger games. Plus, they both run awesome on the Switch 2 with boost mode!

Any other recommendations in the genre?
