This is among the best custom content I've had the privilege of playing, all the contributions from everyone involved in making this have so much quality put into them that I've thoroughly enjoyed the experience from start to finish. Clearly a lot of effort has been spent testing this episode and giving it a high amount of cohesion even though the levels have different authors (and sometimes multiple authors) who imprinted their own personal styles and design philosophies and also which import lots of custom content into them. The many scripted bosses in particular have been a standout and really showcase how fun boss fights could be with some ingenuity and care put into their craft. I also appreciate that the episode provided a good challenge but never felt like the difficulty curve was unfair or that the levels asked too much of me even though I haven't played in ages.
I highly recommend Holiday Hare 24, regardless if you are someone new who is checking out custom content for the first time, have played this game for years, or are returning after a long hiatus to relive some cherished memories and fun times. I think there is something for everyone found here, and it's a great celebration of the holiday spirit of this community.
