How do I make a mechanic with throwable enemies?

dont know if i can do this on the free version

do you mean enemies that you approach, pick up and then throw as your playable character?

dont know if i can do this on the free version

you can do it, is more of events limiting your coding in free version. i think C3 is limited to 30 or 50 events while c2 has 100? not really sure on the limitation, but you should be able to do it, there is no restriction what you can do in those events, outside using the multiplayer/exporting to various platforms/ changing the splashlogo and having more conditions/events than the above mentioned. anything else is game.
