I like the game's difficulty but i've notice that all these Construct plataformers are kind of the same.

The game is too short and even if it where longer it would get really boring.

I retrieved the key. But there was no conclution.

What will happen to our girl? What secrets does the key hold? Is it from a temple? Her house? Her diary?!?!?!?!?!?!?|1111'1?!

I will never know.

I suppose this is just an early trailer for a game you're working on at the moment so I will judge it as such based on the first and only level you provided.

You clearly slow what would damage the character and wouldn't and the transparent platform compared to the solid platform is a nice addition that could make for some fun platforming.

However there are a few problems I've encountered.

One of the problems is that after you die the background sounds will overlap playing the same track twice(easily to reproduce by just going to the left side of the screen multiple times). In addition to this if you don't play at all for a few minutes the background sound will stop altogether leaving you with no sound.

The jumps are responsive but the character animations are not. When starting the game the character doesn't have any animations at all which got me worried. When starting the first actual level I was pleasantly surprised to see actually character animation only to be disappointed again after playing for more than a few minutes, after which the character animation stopped again.

Another problem I encountered was that the character doesn't like platform edges. It could either (in the case of solid platforms) get stuck on them or (in the case of transparent platforms) go trough them in such a way that half of the character is actually inside the platform.

The last thing I noticed is that on your final floating platform the bottom hitbox is still visible (even though you removed this from the other floating platforms)

For now I will have to rate two stars (if judging it as a demo). it certainly has potential but it has some minor starting problems which I'm sure you'd remove before you'd publish your full-game!
