It is good to put these soulful models to good use.
The progression is a bit slow and the game takes a bit too long to ramp up. Too much of the game is just getting lightning or dark bolts early on. The starting sword swing appears to operate based on an instantaneous hitbox that does not match the animation, and makes this worse.
I like the easter egg game over if you run up to the villain.
The power ups could use some description so you can make an informed decision. I got a bunch of health and regen ones that seemingly do nothing.
It seems if you die without getting any points your game over screen will think you have the score from your previous session
The music does not loop smoothly.
Time bombs could stand out better against the terrain
I can't tell how the chest mechanic works. Sometimes it says no key and sometimes it slowly unlocks. I never saw where I got any key from.
I got to 1402 until I was absolutely swarmed by flaming skeletons. I'm guessing that's where the content ends, because the game felt like it was breaking. Overall this is an OK stopgap but I obviously think the main game is fundamentally more interesting. Are you going to have this in there as a minigame or something?
