Biggest issue for me is being unable to see the whole map, plus I tend to lose orientation. I makes it difficult to keep track of where you're doing anything.
"That was a strong rope!" *cuts it with a broken bottle*
Not the best leap of logic. It's still named "Bottle" after it's broken, and it's difficult to see any difference, if there is any, in the image. If not for the "Bottle Broken" hint, I wouldn't have guessed.
Place to put lantern in the dark area was too dark, couldn't see it. A lot of things aren't obvious that you have to click them, which can be a nuisance. Had trouble placing the teru bozu, with it being right on the edge of the screen.
Did you try refresh the game and see if it worked after?
If you're still getting this issue, could you please open developer console (F12) then refresh the game, and send us the logs in the "console" tab, to PM or info@warclicks.com
... After you upgrade the attack damage w/ prestige, it's nice to do bats 'til you can do 6 damage per hit, then focus on snakes. Gives 1 more speed per kill, and is an instakill. After that, return to bats, then do thief after that. If you don't have good defense, you'll also want to kill vampires a bit to get the life steal.
To drag monsters around, to have to drop it on top of another monster, and it switches their positions. It's a bit annoying, tbh. Would be better to just have it so you drag them in between two monsters.
In regards to the negative gains, they aren't really too bad. Aside from the speed reduction on a few of them, which you don't need to fight at all, there is no real bad trade offs. Even for the speed ones, if you just carefully don't use up all your stored speed, you'll be fine.
... How does bury slow anything down? It is just an effect that is applied on yourself at the end of your turn, which increases regenerate's effect by 4x. It doesn't reduce attack, slow your attack speed, or anything.

The game does autosave after wave 5 to the cloud. Plus you can manually save a file on the save button.
