Thx for playing!
1) Cogs has right hitbox. Need to right setup characters to collect it. This game looks as easy game but at start each level need make plan how to complete level. Dont need to fall in "try, rewind, try ,rewind ..." sequence.
2) Precious jumps. Yes you are right, need tuneup some jump points.
3) I think you talk about level 4. This is not a wasting of player time. For logic - what you do when someone talk "YOU MUST DO ........ EXECTLY". In real life you just ***** ignore such request. Level 4 the same - i need stop and think - "what is wrong here?" and dont follow evil instrustion ... after 1 2 3 4 5 6 7 8 9rd attempt :D I see positive reaction on friend faces when play this level. This level not a joke.
Sorry for bad lang (
