Liked:
In the first level of the dungeon where damage and HP are very limited so every fight is a puzzle boss.
The different classes having on map abilities for potential replay value - I picked the assassin which gave some extra chests and an in-combat steal ability (steal a goblin's teeth right out of its mouth)
Decent mapping overall, though the green and brown autotiles visually clash for me.

For Improvement:
After obtaining a class, fights felt frequent and grindy without the earlier tight balance.

Liked:

Nice intro cutscene - is it an Isekai?
Use of shadow pen in town map to make buildings have nice shadows
Mapping in general makes the RTP look better than it ought to
AP skill learn system constructed out of item drops and variables.
Use of busts with face expression edits
Curse your sudden yet inevitable betrayal!
Use of battlers as conversation busts

For Improvement:

If you change the events on the skill tree to "above player" or "below player", then the
player as cursor and the event would be able to occupy the same space, and select the event
where the cursor *is*, rather than butting against.
There are a few word wrapping issues where dialogue and descriptions are cut off - nothing a round
of polishing wouldn't solve.
Screen tint in the cave is a little dark (it's good for cut scenes but a little much for navigation)

This seems to be a remake of your VX Ace game Heaven's Gate. This sort of remake is probably a good exercise in getting a feel for the engine and comparing what you like about it with VX Ace that you're very familiar with.

Liked:
The mercenary nature of the protagonist and interactions with the townsfolk changing as you open more gates.
The respawning treasure chests suit the gameplay loop you have.

For Improvement:
Would like a way to reload the gun without needing to rest at the inn.
This may be a personal preference, but a gameplay loop of fighting encounters and resting at the inn repeatedly until leveled up enough to fight the next gatekeeper loses its appeal.
Some of the encounters in the second area were tougher than the first gatekeeper, so I needed to go back to the desert and grind for a bit.

Liked: Writing and character design match the 1980s action movie aesthetic well.
The whole thing is a romp best experienced by moving forward aggressively rather than carefully shooting everything

Improvements:
I got stuck at the very start, because although the game said to turn off auto dash, it wasn't obvious that vertical jumps would be higher when holding dash.
The motorbike stage I was also struggling with controls.
Maybe add a time bonus for finishing stages quickly as a risk/reward thing for players trying to get a high score.

Yeah, that's exactly what it was originally supposed to be, but I was running out of time, so I just turned it into a joke cutscene pretty much :D I think I will keep the cutscene and add the proper elevator level immediately afterwards.

So, first the good:

I like the atmosphere, the inspiration is obvious, but there's enough uniqueness to stand on its own.

I definitely think this Dark Souls/Diablo esque inspiration has a lot of potential, so definitely keep working on it!

It's pretty cool how the encounters keep changing as you keep getting stronger. So if you lose 600 Light to a bug like I did, it's not THAT big of a loss.

The Skills are pretty good so far, as is the combat. I particularly like how you tried to differentiate weapons, although I am not sure what's the difference between the starting mace and the axe you get by defeating the bear boss, besides the fact that the mace can stun (and does it pretty often) and the axe has like, 2 more attack. So far, the axe seems like an obvious downgrade. Maybe there's something I'm missing?


Now, the areas where I feel it could be improved:

The random encounters are pretty weird. They are both too many and too little? Sometimes you can walk around for minutes without triggering any, other times you get three in a row and when I say in a row, I mean it literally. You finish a random encounter and before you can even move, you immediately get thrown into another one. You don't even seem to have to move to trigger random encounters. I guess you are using some sort of evented way to call the random encounters? One time, I got a random encounter, defeated them, before I could even move I got another one, defeated them too with a Prism, then got ANOTHER random encounter right after before I could even move one tile... seriously, this is extreme.

You should remove the shadows at Mount Eldras. The cliffs project the shadows onto the parallax background and it looks ugly.

The rock pushing puzzles in the cave are annoying, since the random encounters aren't disabled in the area. They also seem to be bugged? I mean, after getting past one and pushing it against a wall, I then moved towards it from the upper side and it somehow moved to the right, trapping me with no way back the way I came. Thankfully, there was a way forward afterwards that included a shortcut to the starting area, but you should definitely look at those moveable rocks one more time, since that wasn't a one-time occurence. And maybe add a Wait: 60 Frames to that event so you can't just keep triggering it as long as you hold the button. That only leads to obnoxious sound effects overlapping and no actual movement. I was holding down the movement key at the boulders and it never moved, only overlapped sound effects. Of course, everything worked once I just pressed the arrow key.

Once I got to Mount Eldras, it started snowing. So far so good, but then I found a rope I could climb down to the starting area and the snowing continued there. In fact, it was snowing constantly, even indoors and inside the cave. I doubt that's intended.

I died to 4 Crows on top of Mount Eldras with around 600 Light saved up. Once I returned to the spot I died at, the light pickup was not there and I was obviously not happy :D Seriously, make sure to perfect this part, otherwise people will just ragequit.
