This level pack excels in having very gameplay dense levels with extremely engaging obstacle design. There's a lot of love and care put into the level design at display here. Levels generally look good, (Jade Tropics especially) and have roughly 3 to 5 minutes of gameplay jammed into them. Lots of vanilla objects are used in extremely creative manners that make some levels here feel very fresh.
Unfortunately, the leading cause of death in this pack is jank; Gimmicks flowing together in odd and often confusing ways that end up killing you. There are numerous glaring visual errors in Software renderer, which can be fixed rather quickly (if there are any you have trouble with I can show you on discord if you message me @othius). The sector and linedef detail often ends up being sloppy, but for the most part is actually very well put together. I think the final boss area has no reason to exist, as it's just a vanilla boss fight without anything engaging added to it, but it's not offensive in any ways.
I had a lot of strong opinions, positive and negative, about the design of this pack which I'll write proper feedback on later in the discussions tab. Overall this was very enjoyable and the approximately 30min runtime felt well spent.
Great work, Welcome to Releases!
