Rad artwork and art direction in general! The monster designs and animations are just top notch. The color palettes used added to the mood and readability of the level design a great deal.
I did have some trouble with finicky jumps here and there though. Be careful of having the player bonk their head/give them plenty of room to make jumps as it kills the fun when you bonk or make things too claustrophopic while platforming.
The lab section was claustrophobic in a good way with its small ducting etc. That was more because i was just exploring small areas and watching the humans rather than trying to platform. I reckon some stealth mechanics in the human areas would be rad, while other sections could be where you focus on open areas with fun platforming challenges, varied enemies like random indigenous alien life etc.
It would be great to have the camera view shift to whatever door opens when you flick a switch and then scrolls back to the player. I was confused as to what about my environment I had changed when interacting with the switches.
Overall it's a great start to a larger game experience. It's not easy getting the playtester feedback necessary during a jam. It's near impossible because of the time frame, in fact. So hopefully this helps!
Really well done!
