Before I start, I would like to say that you should make the background into a different one, like one of the hills that you can borrow from 105 (YI1) or 15 (DP1).
So, I tried it. Improvements can be made:
1) Mark ALL
invisible coins! Don't bother changing only some
. Getting across a gap and finding you need to go through another coin diagonally isn't fun.
2) Get rid of the springboards. It's not fun in any sense of the word, and it's possible to make a kaizo fun, which I would suggest you do.
3) On that note, having repetitive sections (e.g. the run-across-a-ridiculous-amount-of-one-block-gaps-with-invisible-coins-keeping-you-from-jumping spots) is not fun either.
Also, I couldn't beat the first level because of this:
The third parakoopa after the third (!) springboard is too low. I couldn't advance because of this.
I'm not sure about this hack. I looked at the second level in LM. It is repetitive, and for some reason you spelled out "Problem?", in all-caps, in coins.
The interesting thing is that it feels like a satire of kaizo. Stupid hard, unfair, and unfun. Heck, if you weren't so defensive about it, I'd say it was.
But please, fix the errors I mentioned above, and please
don't give snarky rebuttals (e.g. "Is that not what kaizo is?").
If anything above is intentional, please tell me.
