It makes me happy to see you're still here from time to time, raising the bar for the rest of us to aspire to reach. Do you have any plans to look at CCLP1 or CCLP4 ever? (CCLP1 in particular would probably take you no time at all to blaze through.) Have you checked out Markus' SuperCC optimization tool; if so how does it compare to your own programs that you no doubt have made? Is there any chance of you ever gracing us with your presence in the Discord server? Hopefully your life is going well; when you achieve world domination please treat us kindly
I saw that as no different than filling a CC1 walls of level with other acting walls- especially as, given the choice between frame block-> colored floor or colored wall, the wall looked nicer. And really, aesthetic variety was the entire reason why the walls, canopies and, speed boots were added, in addition to the uncommented on monsters on walls!
I think that for a future Walls of CC2(LP1) Create, should it happen, there should be some sort of stricter definition for what a wall is and by extension, what you must leave and what you can remove. That, and for wall-less levels leaving something of the original intact in some way, because without that it's just a level that happens to lack walls- and as H2O's level shows, in CC2 it's not that hard to make a level without walls given how many tiles can act as walls in some circumstances.
Anyway, some thoughts on the other levels... I think Miika's is really clever for how it uses the walls, even if the level itself is "ordinary". H2O's is a terrible walls of level (leaving the force floors behind would have allowed something interesting, I think) but a pretty neat level on the whole, which is a funny opposite to Miika's entry. I think Tyler probably should have won on both use of walls and best level, but I guess I'll take the win for... having the best bonus?
