The game itself is nice, and the level design has no obvious problem. The messages for each one don't connect very well to the actual mechanical challenge though.
The top one makes sense, though I think the yellow enemy seeming more angry or mean would make the context more solid (so it doesn't seem like redirecting enemies to a neutral party). The bottom one is less solid, because when I was actually playing it, the part I ended up focusing on was going through the bottom at the best pacing to keep up the size.
In case it wasn't clear, I think the levels being fun is more important than how well the messages work with them. On that end both of those levels are good.
