Hey i recorded my playthrough for your visual feedback:
I'd definitely say it is a bit slow, with my biggest complaint being not aware of where the door will appear. Sometimes this causes you to basically beat the level twice - the first time to see where the door will appear and then restart and re-plan it out knowing where you need to end.
This isn't horrible, but the fact that the guy moves fairly slow and you can't skip the dialogue makes the game seem like a crawl.
Overall it seems polished and such, but it just needs less downtime for player.
