Great concept to play around with. This creature's lifecycle would be percieved as boring under a normal circumstance but your creative approach to this game ensure you're not just sitting around waiting.
Having the turns pass automatically might have been a touch too far though, I appreciate that, that too is an inversion and attempt to adhear to the theme but it takes away from the opportunity to plan and enjoy the game at a pace where you can enact strategy. I understand this may have been done to enable you to remain stationary and still progress but that could have been achieved by binding a "pass turn" button to the space bar. Its possible that this feature could work if reframed as something other than "turns". Automating turns is a dissonance which I can't personally reconcile, but if you reframed it then I could be onboard with that notion.
Visually the game is coherent but some elements baffled me. For example, I don't know what the various floor tiles do when collecting them.
Overall I enjoyed the fact that you explored an easily overlooked creature and a difficult one to design around. I would enjoy to see this concept taken further.
