Really enjoyed the first three worlds of this hack. I played without the "easy mode" switch palace and found every level mostly fair and made very solidly. The final world though seemed far too different to the rest of the hack - Lots of waiting (fire cave level), extremely tight jumps, colour palettes that were hard to differentiate foreground from background, and some harsh music choices made it less enjoyable than the rest of the game. Although I wasn't a fan of the final world, the other three worlds were fantastic! Really enjoyed the ghost houses
Nicely varied with the themes/gimmicks, and a good difficulty curve. I liked the use of the physics asm here, especially world 2 and 3 were cool. World 4 had some questionable design choices imho - Lethal Lava Kaizo has rng podoboos you have to wait out cycles for, and the music in that level was ear-grinding (why not select the DKC2 lava music for it?). The final level felt like an unnecessarily long drag, introducing no new gimmicks or level styles.
I liked the idea of the "easy mode" blocks, but their placement seemed a little weird to me. A lot of the easier jumps had blocks, but some really tough jumps in the game were left alone. Some examples: walljump level and the hammer bro, lethal lava kaizo and the podobos.
Speaking of Lethal Lava Kaizo... You cannot make it to the 2nd podobo after the blargg on the first cycle. This means the podobo comes out of the lava at different times making the jump pure luck. This half of the level took up 20% of the time i spent on the game, mostly dying to this one jump over and over. This is the only real complaint I have about the hack.
There was a lot of nice paltforming and cool ideas spread around. I really enjoyed the walljump and magnet levels. Also the moles got me way too many times.
