i just kept guessing and restarting the level if you wanna know

this is a really well made map

first result when searching sandbox. Wtf?

Managed to avoid the teleport by just staying as far back away from the buildings as possible.

Finally had my win. The interceptors on their way to me ended up getting stuck on protecting the necromancer, forcing me to go and deal with him, which in turn meant I had to fight everyone else who got aggrod along with him, after who knows how long of kiting the enemies, shooting the ones who would either drop a gun or would make passing the mob harder, I finally won, with the last few enemies being the rock guys, a few mages, and the pyro.

I have tried multiple times to just leave the tiny arena so that I actually have room to dodge and it keeps teleporting me back in. Please fix.

Sempre quis fazer uma voz de narrador bem grossa kkkk

Can you add a sandbox room, This would be more enjoyable if I wasn't constantly scrounging for a weapon while trying to keep distance from the instant kill crabs.

The corpses don't make good shields for the player because the player has to keep moving to avoid being overrun.

eai que e essa voice?

3-About the crabs you are right, they serve as shields for the monsters, but they also serve as a shield for yourself, their bodys (specially the crawler) has already saved me from attacks by minions, teleporters and even other crabs.
4-About the exaggerated strength of the Goons, I updated and fixed this. All of them were with Dark Pirate's Enemy setting, which by default, the Attack Damage is 1.2, but now I changed it to 0.3, but only for the ones that hold weapons.

Ok, here we go:
1-This case of the teleporter being behind the invisible wall, I haven't seen it once, but if it happens again, you can use a long weapon (preferably the double-barrel) and press yourself on the invisible wall, for the shot to go through it, or move away from the enemy and wait for them to enter the arena.
2-I don't know if it's necessary to put a yellow line on the edge of the map to indicate the player on the invisible wall. Playing a few times, you will remember where the invisible walls are, and there are no walls in the middle of the arena, just the edges. If more people want the yellow line, I'll put it in a future update.

A few issues.
First is that a teleporter got stuck and decided to just toss magic at me from outside an invisible wall.
2nd is the invisible walls are too restrictive and have no indication where they are, leading to getting cornered too easily, and also the bodies piling up in the small arena messes with the players aim(also dead crystal crabs and crawler function as cover for the enemy).
3rd is that there's just too many enemies that can kill you in 1 or 2 hits. The fact that I even made it past the crawler section is pure luck, I don't even know how many insta-kill lasers missed me.
