Hammer Dongers is a great idea for a party game, pitting up to four people against each other in small levels with the ability to destroy the very ground beneath your feet.
Currently free while it's in development, not only does it have a good idea but it's also a huge amount of fun because the gameplay is nicely streamlined. You each start with a big Hammer, which you can use to smash the ground and have it fall away to hopefully take down an opponent. With the latest update, they've overhauled the maps with a Castle theme to include new traps and contraptions. There's also a Rocket Launcher because why the heck not.
Have a look at some fresh gameplay:
If they continue developing this and add in more maps and traps, it could end up being quite a hit - I already love it. As a party game, it does exactly what it needs to: make you laugh together. While it's currently local multiplayer only, they will be adding some form of single-player too once all the basics are sorted.
