I love the energy of this game haha; its a one-time meme experience through and through and I thoroughly enjoyed my time. There are some bugs, like the fact that you can't scale hills just by walking up them and the fact that you can't click the menu buttons when dying through jumping off the cliff at the end.
As an experience, the music and art fit the overall mood of the game well and I absolutely died when you had to "pick your poison." It wasn't particularly "hard" to say the least, you can actually run past everything, but I enjoyed my time playing it; especially considering the length of the game.
The arc of the projectiles and the fact that your character was a water bottle made me feel like I was playing Super Mario Sunshine haha!
All in all, if you ironed out the small bugs, or even fleshed out the game a little more (hard to do with the nature of this game, honestly), the completeness would've gone a bit up for me.
