I bought this day one, it's really great. I like the singleplayer missions a lot, they're simple, akin to classic worms where it just gives you a particular battle to win on a map, usually with a unique theme or orientation based on using certain weapons and gadgets.
Visually, the game looks great, and for me, performance has matched that, absent of any significant frame rate drops. This is significant as previous 3D games chugged on PS4, and ran even worse on my laptop. I remember missing turns and messing up because of performance issues in those games, but not here, where it seems to be smooth.
I like the new vehicles, building interiors and crafting systems too. They work great, none of it feels overpowered, but offers new spin on the existing formula. Significantly, the crafting system allows you to really cultivate specific plays and strategies in ways that wasn't possible before. They added something similar to this in the previous iteration with the coin mechanic but it was still pretty rigid as you couldn't always acquire coins. Now if you want you can dismantle weapons you don't need, to craft those that you do.
I miss the water though, drowning worms in the previous 3D games, forcing them out of bunkers and whatnot, pushing them down hills to their death, the liquid mechanic was fun and they could have expanded on that. I think if worms wanted to then more physics orientated features would be really cool. They should look at Pixeljunk Shooter for inspiration, I feel that the water, lava, and ice mechanics in that game would be a good fit for a 2D worms title.
