I'd love to give you more opinions. I'm glad that you didn't give those typical "if you can't beat it, you suck. Go play something else!" answers.
One thing that made it hard is that there are some things that are not very obvious and didn't exist in other Notrium mods, but can doa lot of damage. Especially in the crystal region, where the crystals would grow and eventually explode then you hover your cursor over them, and those ghostly creatures leaving mines that explode after a certain amount of time. Of course this is what I discovered after playing long enough. My first impression of that area could only be described with one word: chaotic. Here's basically what happened:
*Walk into the area*
"Wow, those crystals are mines. Better stay away from them..."
"What's with those moving sand?"
"Oh, 'edible eggs'!"
*Munch munch munch*
"Doesn't really help a lot..."
"Woops, the mum gets angry... run!"
"Aha, they don't really hurt me..."
*Boom!* *Boom!* *Splash!*
*Beep... Beep... *
"What? What happened? They made the crystals explode? Better get outta here!"
*Boom!* *Zap* "Ouch! Those damned blue plants!" *Boom!* *Beep! Beep! Beep!*
"Why can't I outrun them?"
"Oh what the... countdown?"
"Oh well... can someone tell me what 's going on?"
Another thing is that there isn't a "safe area" like the hermit's house in original Notrium or Weriver mods. Not that there has to be a safe house, but getting attacked endlessly without any means to defend oneself (not even punch) is somewhat frustrating. The items, especially the most important of all, the weapon chassis, are too hard to spot. Right after I started, I picked up every item around the ship, everything except the weapon chassis, and started exploring the area. After being killed a couple of times I realised that I must find one in order to build a weapon and survive, so I started searching for one frantically. After being killed for few more times, by several different creatures such as the blue slug and some pods that pop out from ship wrecks randomly, I finally found one just beside my broken pod...
But finally I was able to build a laser gun, and used sniping and guerilla tactics to kill a blue slug. Luckily they don't seem to regenerate health, otherwise it would be practically impossible for me to kill them.
I understand that this mod is still in early development stage, so I didn't expect so much. The graphics and planning are great, and it surely has a great potential. I hope in the future we will see a much more refined and complete mod, and won't be abandoned quickly like many other mods.
