Superb gameplay, but something's missing.
Fantasitc game! Fun, challenging and the extra achievements are a huge plus! I just finished earning the Huge Achievement and I thoroughly enjoyed myself the entire trip. I have only two gripes:
1. Lack of an ending - it was a let down (to say the least) after sending the 20th part down the tube to see nothing but the stage selection screen. After I got the same after redoing the last stage in order to beat the fast time I was rather disappointed. Some clip of the final invention would have been much better - and after the huge achievement would be a perfect place for an even better ending (if one or more ending video is hidden somewhere, I'll change this point to one where I suggest automatic display the first time you see the map screen after the appropriate accomplishments).
2. Uni-directional magnetism - frustration ensued multiple times when I released my magnet only to have it be facing the wrong way and thus neccesitate a tedious repositioning (or even a stage restart if I was going for a fast time). Having the magnet work in all directions would have been a huge decrease in frustration while providing a trvial reduction (if any) to challenge.
Thank you for sharing this game with me.
