First, ibwun's .ips is
right here.
Alright, this is pretty good! The level is paced nicely, never gets too hard, and is aesthetically pleasing. However, I can't accept it. I feel that a lot of segments are empty of "animal" sprites, especially in the second part (sort of just Thwomps and Ball'n'Chains). If that's remedied, I will accept it. Other things to notice:
Missing connector tile. This area also seemed sort of useless to me.
Just wondering, why the extra Ball'n'Chain?
The pipe seems needlessly high, and I have trouble spin-jumping onto the Thwomp without getting hit. It's very hard to get up there without spin-jumping.
That palette doesn't look too great. This was also an emptier section.
That Thwimp gets a little glitchy stuck in there.
Miniscule, miniscule cutoff on the underwater corner of the castle block. I'm not even sure you can fix it, it's so minor anyway.
I feel this level is almost there, just make it more full and less barebones. Remember, you can always use Dry Bones and stuff.
