Very creative premise for a game!
Unfornately didn't get to enjoy it that much, the lack of polish and a lot of funky bugs I ran into were quite annoying such as the head would sometimes freeze for some reason, it'd also be nice to see the amount of money I have currently for buying upgrades.
I have a lot more to say but I'll leave it at that for now.
omg yes! I have a 2k monitor (1440p) and I couldn't see those UI!
I'd suggest stuff that could elevate the gameplay more, such as maybe incorperate the giraffe part more and lean into it, such as maybe ragdoll physics or tiny bit of weight for the head to make it feel more like a giraffe, different types of windows, or give the player the controls for the elevator.
These are just some stuff that I think could make the giraffe part more prominent!
Other than the basic stuff such as Music and SFX, especially with games like this, having a squeaky clean noise (the satisfying ones), would be quite nice, and if a window is fully clean, make it shine to communicate to the player that it is fully clean.
There's a lot more you can do! I believe that you can definitely keep improving as long as you keep trying ✨

Thank you for the feedback! I will plan out a little bit more time for polish in the future :)
