Worst enemy movement and hit detection ever. It seems that as soon as your zapper gets within a certain radius of the bug, it will go the opposite way. If you go too fast and go past the bug, it will immediately turn and run the other way. This means you can't really click on a bug, you need to trick it into going through your crosshairs and click at the exact moment. But the hit detection is not very good (way too strict), so it's really hard to hit the bugs. Extremely frustrating, not fun. 2/5.
That was interesting. Not very fun in the end though, 2/5. I did like the retro graphics and sound, but randomly generated enemies are not interesting.
I don't think I've played an adventure game all the way through since Day of the Tentacle. Most of the puzzles were possible to figure out, given time. However, making the item to open the damaged cargo container was not. I'm not going to put in any spoilers here, but it's definitely a "try random objects together" puzzle.
Overall, the artwork and style of this game were great. And that, combined with good puzzles, is what makes adventure games good.
