This is probably the best game out of the series because it has a few puzzles (more like mini-games) that you need to think about - at least a little bit, but it's thankfully not like a couple of others games in this series where you don't have to think at all. There is one in particular where you have to move a light around a screen that could really have benefited from a keyboard control option, and the avoiding the debris section right at the start doesn't look or operate that great in my opinion, but other than that they do add to this game in a way you typically don't find in point and click adventure games.
It's a great shame that after all that effort, there wasn't any kind of ending - just that meaningless score again. There's potential for 1 more game because there's still a certain mystery to solve with your old friend Venus, so I do hope there's another game coming. Overall I enjoyed these series of games, I'm glad I played them, but I felt at times the execution could have been better, and there seemed to me to be a slightly uneven standard of quality between the games.
