I played through the whole thing! I can't imagine this was easy to make.
I'll give you some constructive criticism. I think a menu system here would have added a lot, and a level select to give the player a sense of how much progress they've made. The big thing I learned after making my first game was to think hard about the controls, because what's intuitive to you might not be for other players. Here I think W to jump is a little odd, and its a bit temperamental. Space to jump and E to pick up objects makes sense to me. I think some of the puzzles are a little over designed, for example there is one near the end with two lamps, a button, and an orb; the lamps and button are completely unnecessary to solve the puzzle. Ideally each puzzle should teach the player something new; there was a string of puzzles where the flashing orb was introduced in which the exact same solution could be applied to three puzzles in a row.
Your puzzle with the two sticky orbs (in your screen shots) was the best one. It really made you think. The sticky orbs in general were a great idea. I feel you could make a whole game involving just those orbs; you could make a really interesting level with three or four of them. Also the puzzles involving throwing the orb were dope. I think you have some really cool ideas here and you should definitely be proud of this.
