I've tested the map watadry_beta3,
but replied in a wrong thread.
I was playing on a phone, so my experience may be biased.
Once you've learned all the map shortcuts, you'll make gameplay frustrating to other players (also, bots are easily confused by this map).
There are two shortcuts to the enemy base, via underwater way and teleporter, and there are too many escape routes after you grab a flag - run to the jump pad, collect the health and armor from the upper gallery, then there are two routes to run away from the gallery without jumping down to the open space, and you can grab a plasmagun on the way back. Once you around the first corner, you're safe - there are too many sharp corners on the way back, so it's impossible to chase and snipe you down, you can also grab megahealth while running to your base, and run away even without shooting. But if you're killed and respawn on your base, there are no decent weapons around you, you need to run ahead, and it's not unusual for flag carrier to grab your plasmagun and rocket right when you need them most.
The best strategy for flag defenders is to stay between two bases, where the megahealth is, the flag carrier will have to run across that area.
Also I dislike that lifting platform that goes up and down at regular intervals, it's easy to get squished. Why not a plain jump pad?
I was able to jump to the teleporter only after 10-th try, and the underwater passage is also not that easy to use.
The texture choice is okay, and illumination is also okay, although there are not too many variations, just the same ambient light everywhere.
