Been playing the previous version before the one you've submitted in the thread today. The hack is pretty good and challenging. Most of the issues found are minor and are related to some minor cutoffs, a few blind jumps, slowdowns and A Coins and normal coins not appearing (I think the coins issue can be fixed by setting tile memory index to 3). Anyway let's go with the issues:
Friendly Fields 4:
1. Some examples of the semisolid using the wrong tile (sides filled with dirt instead of only the sides):
2. Both of the pipes can be used to access the main cave level:
3. There was supposed to be a hidden block, but an used block appears instead:
Green Switch Trial: A small blind jump there:
Miracle Mountain 1: Cutoff between the water and the pipe, you can use some ground so it can look better:
Miracle Mountain 2: Both pipes can be used to access the sublevel (Mario comes back to the main level with the second one):
Miracle Mountain 4: Glad you fixed the goal and overworld issue! A minor thing is that the semisolid cave tiles (secret exit sublevel) have the same issue as in Friendly Fields 4:
Miracle Mountain 6: Minor cutoff between the semisolid corners and the rocks over them:
Striving Skies 1: Another used block instead of a hidden block:
Striving Skies 2: Cutoff between the pipes and the cloud FG in the bonus area (you can use the square blocks under the pipes):
Striving Skies 3: Cutoff between the Bullet Cannon and the cloud FG (same as in Striving Skies 2). Also, the cannon in the lower part hasn't the tile with the skull. Not bad at all but kinda weird:
Striving Skies 4:
1. A Coin and some regular coins didn't appear at first, but when I replayed the level they were there:
2. The platform can disappear at times, very unlikely but still:
3. Cutoff between the goal and the cloud FG (blocks under the goal will fix that):
Striving Skies 5: Some coins don't appear in the bonus area:
Striving Skies 6: Cutoff between the checkpoint and cloud FG (again blocks help there):
Radical Resort 1: Mainly a bit of slowdown in these areas:
Fun fact: you can farm 1-UPs there:
Radical Resort 3:
1. Wrong tiles in the upper corners, causing a minor cutoff in the underwater sublevel:
2. Both pipes can be used to access the next area:
3. Slowdown:
Wisdom Woods 1: Some wrong corner tiles through the level. Also this the only level where spiders' sprites are glitchy:
Wisdom Woods 3: A Coin doesn't appear at first playthrough:
Wisdom Woods 4: Blind jump:
Wisdom Woods 5: Some players can confuse the decoration with actual cimbing vines. Also these ones are floating:
Wisdom Woods 6: Same as in Wisdom Woods 1:
Gratitude Glacier 1:
1. Glitchy fireballs (piranha stems) are shooted from the cannons:
2. Another A Coin that doesn't appear. Also, this the only level with 6 A Coins:
Gratitude Glacier 2: Some slowdown there:
Gratitude Glacier 3: Wrong corner tiles (down looking right ones):
Gratitude Glacier 4:
1. Some players can confuse the falling splike with a normal one because they use the same palette:
2. Slowdown:
Eternal Empire 1: A Coin not appearing in the second sublevel:
Eternal Empire 3: Another A Coin which doesn't appear at first. Also, there are only 4 A Coins:
Empire Fortress:
1. Lower cannon without the tile with the skull (same as in Striving Skies 3):
2. Slowdown:
Eternal Empire 5: Another A Coin issue:
Ultimate Utopia 6: Wrong corner tiles through the level:
Most of the issues are minor and the hack is a great work!
