So about the glitches there's a major one, where sometimes and only sometimes you spawn in the ground when you lose, and you have to restart the whole game, it can get annoying overtime but it's playable I guess.
The game idea is amzing a speedruning dead god or something lol, but the movement is kinda janky having the speed really high makes it uncontrollabele not faster.
Here's a great source for making better character feel :

but good game overal ( I especially love the color palette )
