This is gorgeous, and the controls are pleasantly responsive (which is often a problem with metroidvanias). But...I think I got myself stuck? There's a blue pennant, and to the left are some spikes; above me are platforms I can't reach; and back to the right are a few pounding device things, and also some platforms I can't reach? Maybe I wasn't supposed to get down here without picking up some powerups? (But here I am.) Am I missing something?
I am in the exact same place. And this is the second time I ended up here.
Edit - Went a different route and got the double jump.
Then got the dash ability.
And then... on reload both power ups are no longer working and the only route available ended up leading to that initial one that you posted that you cannot get past without the power ups.
I guess I'll check it out when the bugs have been addressed. Lots of potential!
