Love the game, but there are a few mechanics that don't make a lot of sense and can turn the game from challengine into actively antagonising the player. I know it's probably not easy to adjust because of existing mechanics, but I'm still going to mention them.
One big one is water. Had many casses where a few pixels of water (basically the height of the feet) ragdolled the experiment. A creature weighing ~40kg should not be pushed around by 2cm of water (not talking about when a geyser pushes water out, that makes more sense, since, yeah, it's supposed to be a trap).
Another is a bit tricky, but let's call it "lack of self preservation". 2 examples I encountered:
- Experiment was severely dehydrated. There was lumalgae around, so I drank that. Experiment stopped behing dehydrated, but got so depressed from drinking the lumalgae, that it blew it's head off with a shotgun.
- Experiment was very sleepy. Tried to sleep, but got pushed by 2cm of water and fell down into a puddle that was torso deep. Experiment was so sleepy that it started to take a nap, drowning in this otherwise harmless puddle.
Not gonna lie, I lauged my ass off when these happened, but thinking about it, it just feels weird.
As I said, I love the game, and will keep playing despite these small shortcommings. It's a fun and challenginge expirience.
