As I understand it, the author intended that to open the prison, you need to kill 2 stacks of dragons on the islands, and then you can open the prison. But it's not interactive... and it's not important either, since everyone just breaks through it. The author got confused with the order of the scripts, but the map can be completed.
better late than never! lol
the idea was that it should be like this:
in the second valley, you meet goblins and druids - a fork where you can choose who to help (goblins hunt elves, elves want to escape the valley, but they can't without ents).
in the third valley, there is a prison with ents. it is locked with two keys on the Yin and Yang island.
you save the druids - they help in the battle with the boss of the second valley (who is actually already defeated, because you only get to the third valley after defeating the boss) - this is where the script breaks.
then the goblins should be offended, and they set up several ambushes on the map.
if you help the goblins, the goblins reward you, help in the battle with the boss, and that's it. or maybe not. I don't remember anymore, lol
conceptually, the mistake is in the order of visiting locations. but I did everything quite spontaneously at the end and didn't finish it, alas. this is really my first map that I brought to the finale. it's too big - I took on too much and got a little burned out. maybe one day I'll make a remake of this map in a much better version, a little smaller, but no less interesting. let's not wait, but prepare: P

Yes, it's possible, I finished it. At the end, something didn't work either, and for some reason, instead of a mega-devil and a succubus, I had ordinary ones, and on the way to the god, the same heroes were not strengthened at all. Good map (especially the first half in terms of gameplay, and I like the design of the area), it's a pity that it wasn't finished. And if this is the first map, then it's just great. Thank you to the author.
I'm glad that you liked the map even in this inadequate form. maybe one day I'll redo it.
you're welcome.

Thank you for the map, I really enjoyed it, I played on veteran with an angel, what can I say about the map in my opinion, a chaos hero and one like that is a bit too much for me, but overall I liked it), I also liked the style and the separation of areas, I would also like to evaluate the balance of the map in general, in principle, it can be even more difficult, but I played on veteran, so I can't say for sure, the bosses are very good, they are difficult and annoying in a good way, the balance is well maintained for people (due to training), it is quite difficult to make it, I will give the map 9.5/10, I really liked it, I finished it in one go)
damn. even I think it's tedious. well, the customer is always right, of course! lol. you're welcome.
