Definitely an improvement with the new engine, hope that the next chapter can work the kinks out of it. I'm sure you're aware of these issues, but I feel I should list the ones I found just to be sure.
First, resetting the level didn't actually reset the level it seems. On the death screens, hitting V just made the death screen replay, and after the chase scene, it just causes the ghost's blue orb form to chase you right away, even though you're back at the beginning.
Second, the wall clinging thing seemed more of a hindrance than something helpful most of the time, as you'd jump and get momentarily stuck on any vertical surface, and you only seem to be able to wall jump in the one vertical section of the map, so that's the only place you really need it.
Then there's the resolution issue with the text, which you've already made clear you're aware of so I won't go into that too much.
There was also this thing where it seemed bits of the intro text stayed on screen after it went away? Like there were little white dots left all over the upper part of the screen?
Last issue I had is mostly personal, but having the punch button be Z really made the chase scene hard to play. Having to hold down D, shift, and press Z to punch goblins as you run really made it harder than it needed to be. Honestly felt like the run speed should have just been the default speed, since the walking speed is painfully slow and the sprint speed isn't really that fast.
Anyway, those are all of my thoughts. I look forward to what you do going forward!
