A very cool idea and approach to the theme, like the robot and sound effects used. However pumping and the timing is very hard to master, and putting the level of combining everything after just a few tutorials makes the flaw of pumping the air from an interesting idea to a very tedious and boring one, especially sometimes the mouse click/drag don't register on the pump. Making it quickly become frustrating instead of feeling interesting.

The gameplay is quite interesting, made for quite a fun game!

One complaint tho, maybe increasing the pressure would've been better bound to a keyboard button, like space or something, it gets quite tedious to pump it with the mouse.

Other than that, pretty solid for your first game! Keep it up!

Great work, little tips for the future tho:

-The pumping gets tedious after a few levels. Gameplay feels slow, to much waiting winding up the propeller, waiting for the pressure to decrease etc. Makes it also feel unresponsive, and overall frustrating. 

The game's proposal is cool, but using the pump all the time is boring, good job!

Using the pump is pretty tedious but the Idea is good I'd say.
