Don't call me Indiana!
Sega really did a geat job with these Disney licenses at the time. Not only do they look great, but gameplay is usually on par with if not better than Capcom's work from around the same time and a couple of years earlier (when Disney shows were arguably reaching their peak).
Similar to DuckTales 2 and Land of Illusion this is a MV-lite game with a hub map, where you travel the world and gain tools and weapons used to progress. Sometimes progression also requires revisiting a previous level with a new tool (generally a marker is placed where you couldn't progress before so that you can fast travel right to it on your next visit). Besides a plunger gun that you can upgrade twice for more traversal options (the red one basically lets you create your own platforms wherever there's a wall to fasten them to), you'll be able to shoot lethal popcorn (!) and lethal bubbles which also remove certain blocks in some levels. In the levels you can also pick up peppers which eventually end up sending Donald on a rampage where he moves quickly and takes everything in his path out simply by touching it - a move that feels true to the character and brings a nice change of pace to an otherwise mostly mid-tempo game.
The controls are solid and if mastered there are some tricks you can do using a slide move to keep momentum high and pull off some minor sequence breaking. The level design is pretty inventive with some decent puzzles here and there, and it's quite varied too though some ideas work better than others (a low point is having to backtrack out of a dungeon instead of getting teleported out). The game also features a good minecart segment, which is always a plus in my book.
As with the other games I mentioned, again I just wish this was a level or two longer and had a hard mode as well as a save feature.
