OKAY. maybe I was impatient. LET'S ROCK THIS!

PoliuxDimension responds:

Hello, how are you.
New players or old players please watch this...
I patched this game to version 1.2 on 2019/5/27.
The fixes include:
1.I narrowed down the hit boxes of the stalactites in the caves to its very center.
2.I narrowed down the hit boxes of the thin waterfalls and move it toward seifu's side.
3.The wide waterfall was also be narrowed down to its very center
So those unreasonably hard to pass maps should be a little easier now.

You can also now customize the movement key to other key in the Q menu.
And I added new key T, to reduce your HP to1.
If you want to retry a boss quickly, just press T and get killed by the boss quickly.
The T can also be customized to other key in Q menu, thank you.

ofc 5 stars its awesome game

PoliuxDimension responds:

Thank you.

gud i guess.

its hard

far more deadly then ancient demons.

The bosses in this game are great in a dark souls way.
The 2 platforming areas however...
The way the main character moves and where the hit boxes for the water falls and stalactites are brutally hard to judge.

Only other minor gripe is that there is no quick way to return to the previous save point. This is only really a problem when your trying to do the "in your face" achievement, because she takes a long time to kill you, so you get stuck just sitting there waiting once you inventively get hit and have to start over.

I did enjoy the rest of the game.
tutorial and stalactites took an hour total
the water snake took 3 hours,
the flying girl took 2 (to beat anyway),
demon was my fav fight as i had to rely on both audio ques and visual points. took 4 hours
the first time through the waterfall area took me 6 hours across 3 sessions...
and the fox took me literally weeks of trying.

i'm writing this review from round 2, as a way to vent about a certain no damage achievement.
In conclusion, would recommend if you like a hard but surmountable challenge

edit: noticed a visual glitch that shows the death animation for me when you enter the cave within the stalactite area, but you then enter the next zone.
and yes, im alredy on round 5 like a day after that review X/

PoliuxDimension responds:

I bet your second round will be much faster than the first one, and I'm willing to hear how long it will take for each boss in your second round.

I made hit box of this game too wide i guess, I will try thinner hit box for traps in my future games.

I shall find a way to create an item or a skill allow player reload to last save point at some cost though, it would be a good idea anyway. Currently you have to do that by suicide in the fight.
