6 Feet Under is a great game, as said in the description, the game is more focused on the speedrun community but if you're a casual player, this game is also good for you.
The overall gameplay is exciting and can keep you focused on finishing the levels, if you master it correctly, you can keep up your momentum so you sure will finish the levels faster than before, it takes time to know how to control the zombie-drill properly so don't get frustrated so easily.
The graphics + sounds are simple, it reminds me of the Gameboy era, it's stylish, cute and retro.
The game's levels are perfectly placed and if this is your first time playing you will spend a short time trying to find the right place to go to point B, as I said above, mastering the drill controls is something that takes you a while little time so spend that time trying to learn about the levels while trying to control your momentum.
