Ok, cool.
I was literally just scrolling through Newgrounds games trying to find something that would immerse me instantly, and challenge me without a bunch of reading or background exposition or complicated mechanics... thank you !
There's a lot of merit to games like these. I instantly was encaptured by the simplistic art style and quirky walk cycle. The sound when you take those steps is super gratifying. And the music was well picked, since it's not overwhelming and instead it's cool and calm, just like how someone should be when playing a puzzle platformer.
The game mechanics are great. Jump on bubbles, get collectibles, avoid spikes, and press bouncy buttons. What else does a man want? Well, at little more would be nice...
Here are my complaints.
The problem with having a simple concept is being able to create enough unique situations, that don't become too complicated for the user. After the first ten levels, I realized that the wall jump mechanic is going to be 70% of the game, and it was. You could've avoided this by having walls that don't allow bubbles to adhere to them, forcing the player to actually use the environment instead of just blowing bubbles. Perhaps a ducking mechanic so the player could avoid hazardous projectiles or fit into places that bubbles couldn't.
When I had to use the button to jump higher to grab the carrot, I was super excited. I was like, "Wow! This could make for some interesting situations." But you didn't use that to your creative needs-- you could've made some cool schemes where the player had to fall onto a bouncy button, and make the next gap.
The spikes showed no variation (besides some being on the ceiling,) and those were as predictable to deal with as anything else: blow a bubble and jump on the bubble. Having some moving spikes or spikes that pop bubbles would've been awesome.
The bubble absorbs carrots, but why not have it pick up some other things, too ? What if you had to blow a bubble to capture enemies, or hazards, so they fall off the edge?
I think you did a great job, but I see the lost potential.
You should really come out with a second one. *thumbs up*
