Last part aged quite poorly but rest is very good for the time. Has definitely aged significantly but it's one of the most successful collabs of its time for a reason. Frozen Cave has a vice grip on its theming throughout which cannot be said for most megacollabs of that era. Unfortunately, the constant juggling between a more detailed style and a more cartoony style does not pan well for it, as this causes the visual consistency to be basically nonexistent. Not to mention, both styles used are not executed very well by today's standards, having really shoddy colour usage throughout. With the exception of the first part, all of the parts have very glaring issues that make the level as a whole look kind of like a mess, and not in a good way
