Cursed Legacy

Really great game, enjoying it a lot.

but I have a few questions left:
1. is there an actual end?
like I have explored everything , got all 4 pieces but have no idea hwere to go. like is there some place to trigger an "You won the game" kind of thing? or was it jsut not implemented?

2. as said, I explored everything, all shortcuts and nook, severything that is possible with double jump, wall climb and dash.

however 2 places I still couldnt get too:
a) from what I got this game is 4 by 4 screens, so 16 in total.
on the top left most screen, there is an area up ahead that I cant reach no matter what. you jsut cant jump high enough with mere diuble jumop to even reach the wall, let alone climb it.

b) this one probably holds nothing but the xompletionist in me wants it:
start at the bottom right msot screen. go one screen left
(a mostly empty very simpke are with many bats)
I would love to explore the top right area of that screen. however there is no platformy way to get there. and the right wall is to high to touch.

any way to reach these 2 places?
I highly doubt that I missed any mayor powerup or anything.
I would even go ahead and say that I got like 90+% of all damage and health upgrades
(not 100% cause I tend to stroll past areas that I previously already explored, thinking that I got there already so there must be nothing. but forgetting that one place at the start that I went by and couldnt do due to whatever. so yeah, I tend to overlook stuff in already explored places.)


so yeah, basically is there an end flag anywhere?
and can these 2 places mentioned above somehow by reached? :-)
