It has a nice atmosphere, and the concept of a Metroidvania that incorporates endless runner mechanics is an idea that has legs (hardy har)!
Unfortunately I didn't get very far. The game doesn't seem to be registering the checkpoints, and in some sections, it stops registering jump reliably.
I thought it might be my reaction time or hardware, but it happened a lot in the section after getting the respawn power. (Which BTW, didn't insert a control prompt in the ability description.)
Other than that, maybe the flowery dialogue is a little too long. I enjoy a bit of old-timey prose to set the mood as much as the next guy. Just maybe compress it down to a third of the duration, so it doesn't interrupt the endless runner flow.
As a suggestion for if you develop the game, obviously you could have stopping points and save points to teleport two and throw, but maybe some kind of device that allows you to switch direction, so you can explore different paths without stopping.
Say like, a dreary street-lamp that the character can grab and swivel around id the player's holding a certain button that sends them down a split path.
Though if they miss the opportunity and have to take a long route around it could be frustrating... but I reckon it's worth playing around with.
I got some gameplay recorded. I'll post it when it's up.
