Very cool concept and the art is really cute. Love that the enemies can also possess the weapons, is really interesting how every now and then you end in a little race with another ghost to pick a weapon.
For a feedback i would probably make the game a little faster at first as it is a little to easy once you understand the idea (you could attach the difficulty with the amount of enemies defeated, so the better players will find a challenge faster and the more chill, can progress at their own pace). Also the cooldown of the attack should be (in my opinion) communicated in some way, like a progress bar.
Also the hitbox in the enemy spears can be a little misleading.
The game concept is solid, in my opinion, just needs a little work on the juiciness/gamefeel.
Congrats! (and thanks for playing our game on stream)
