Slimes

Can't seem to kill them, every weapon I equip gets swallowed, punched them a thousand times and nothing... and this on the second level.

Am I doing something wrong?

I am sorry to hear that.

They are really annoying type of the enemies, and they got slight changes in next release (which will be released in a few weeks), but there is certainly some other problem with them. I will look at them a bit more.

Unfortunately punching doesn't work always. By selecting the enemy (with TAB) you can see damage that you can inflict to that enemy. 

If you can't inflict damage to them, try to avoid them. By hugging the walls, you can reduce your noise (you can see your noise in upper left corner of the screen labeled as N4 for example, or visually by pressing 'N'), or by trying to hide ( press H, which will effectively reduce your noise to 1). This will make enemies less likely to attack you. Note that, plate and mail armors make more noise.

Spoiler:

Moreover, slimes are not 100% finished, there is one missing point I still need to finish.  Slimes should be easily distracted, and green slimes especially by throwing food  away which they will consume. I see that there is a lot problems around with the slimes, I will try to squeeze this missing point in next release.

Hey there, thank you for the reply!

So it's a combination of me doing something wrong and some coding :) Glad to hear you are working on it.

Kudos by the way on the game, it looks fantastic!
