At last, a chance for revenge for previous criticism received!
Just a cursory glance here and I can see a few issues.
First up,t he small fireballs. They look like items, especially the yellow\brown ones. These need to be bigger, more vicious looking, more solid maybe. Like the light blue electric things.
Second, backgrounds. Need more detail, but not much more. For example that \\\\ background of yours would look much better with the addition of a simple reversed tile \\\ Then you could make all sorts of background patterns with it, with just one tile more! Your foreground tiles also could use random blips in them, even things as simple as random gears, lights and buttons. Just something to break up the space. Inventiveness does show through; the red-blue towers for example.
The Engrish is indeed hilarious (Hungrish?)
The Star Dock does not look like a level, it is almost impossible to enter.
The drone things need to smash Keen's shots, right now the shots just pass right through. (This is easy to do.) Same goes for the square guys.
Some direction arrow tiles would be nice. Maybe a big red 'X' for dangerous places.
The blue robots need foot rockets or something so they look like they are hovering in the air.
The Bloogs need to animate more, they look too still right now.
Blue ground slopes mess with the pogo in an odd way.
Rocket A needs doors for Mart to be able to get back down faster instead of having to go from the top of the level all the way back to the bottom. Maybe also a switch and platform to get to an area near one of the blue balls as a treat, or some poles to climb, even if they don't go anywhere.
Mort's lab is well done. More like that, especially the backgrounds.
Tile mistakes:
(In this one it is a line in the blue ground.)
Here I can jump up right through the floor from the secret passage. Uh-oh...
Can this jump be done in hard mode? I cannot get past without cheating.
Bloogs get stuck if they reach platform edges:
What you really need, not what you think you ought to want.
