Wow dude, great game!
I loved the music and soundeffects.
Did you make those yourself, or can I get them somewhere for potential future games?
Usually I quit a game after a couple minutes, but completed this one, because of the elegant way in which you scale up the difficulty for each mechanic: jumping, hooks, balloons, ray man.
And also in the timing between introducing new mechanics.
Especially liked the hook mechanic, it's really cool.
In some levels you could take an easier path but not collecting the hourglasses.
I always took the hourglass path. And at some point there wasn't even an hourglass there but I still took the more difficult route, because I got so accustomed to : difficult route = hour glass. Loved that surprise when I realized , wait why am I going here?
Some improvement points: why am I collecting hourglasses? Didn't read all the help messages, but this was something important that I needed to know, would have made the experience feel a lot more meaningful to me. Nonetheless I did collect all of them blindly.
Controls: sometimes I wanted to jump and hold movement key at same time, and it wouldn't jump this is a minor thing but gets really frustrating.
Also add in aswd controls.
Nice game, looking forward to your next
