Super Blood Hockey. 80% off, about $3 USD.
It's a very well made pixel art game where you play hockey and you can beat up the other team. There's a franchise mode as well, so you'll want to balance how much fighting you do so your players don't get too hurt. There's local co-op so you can play against friends (or use steam remote play together).
PlateUp!. 40% off, about $11 USD.
Similar to Overcooked but you need to manage your restaurant and make sure you don't fail a single order. It's a rouge-lite, and you can move everything around in your restaurant and you kind of manage the menu as the days go on, but you get a choice whether to add option A or B, so it slowly gets more complicated. Very fun with friends, steam remote play together works here as well.
Bone's Cafe. 30% off, about $11 USD.
Similar to Overcooked and PlateUp!, but I feel like it's more geared towards single player (but there's local co-op as well). You have to manage your restaurant and menu (can make it as easy or complex as you'd like), while also maybe killing customers to harvest them for ingredients :) You can spawn in helpers and you can show them a repetitive task to do and they will do it.
