Great game, nice memories from the past. Really like 2D style. I hope it will be released on Steam for greater audience.
My only issues with G5 are
1. you must repeat some actions like 3-5 times. you must break all boxes, you must clean all flowers, you must make all kids happy, you must <action> all <objects> and so on.
2. the lack of classic cooperative puzzles like 1 goblin get a plank while 2nd goblin lifts the safe.
