It is not sticky situation. I think that It had been sticky for those people who have played that game. All are awe about it option. When I have played it first time I have also faced that issue But When I have surveyed more then I have found it very well and enjoyed the game.
This helped quite a bit, although there was no way I could use the spider on levels 40, 45 AND 50, despite following instructions to the letter. I had to find a way to beat level 40 without using the spider, and I did so by temporarily adding a fully-upgraded laser. I then sold it until following step 4 above, so that the spider had time to recharge between level 45 and 50. After a RIDICULOUS number of attempts, I finally got perfect on this level.
It works! Thanks. You can add a small gun near the door in level 50 to clear up the remaining objects thus getting all achievements.
