A brand new 8-Bit game that is published but not developed by Yacht Club games.
It does have a Linux release and early impressions of the game so far is that it's a platform adventure that is mostly linear unless there is a glitch that breaks the game which isn't going to be likely.
The main selling point that will make a run "SPEEDY TAS of the Year" worthy is part way through the game where Shadow learns both the dash and dash slash techniques.
The latter can be spammed to be faster than normal dashing but if the player has at least 1 SP the dash can be extended and in some cases, killing an enemy with a SP Dash Slash can lead to another (SP) Dash slash.

Shurikens are ideal tools to kill grounded bosses in the early part of the run for having good DPS.
Rising Fire is great against Mekadragon who is pretty RNG based where it spawns although in my first playthrough when I hear Mekadragon's BGM playing, I go to the far left and got the first spawn very consistently.
Parry is going to be a huge factor for the TAS as it can negate projectiles and reflected back for bonus damage.
The secondary items have some uses.
Extended blade will be handy for early hits against bosses but other items like swag blade (yes that's the actual name) has actual long reach with a yo-yo like effect.
SP Dispenser will give +1 SP to the player after a few seconds, very handy when sprint is unlocked for more SP boosted Dash slashing.
