Its very great
very well written
I love it
The story takes a moment to grasp. I kept being interupted by my own questions about the possibilities of what could happen. The music really carried the flow of the story. The art style was perfect, simple but not simple enough to throw off the idea that the story was about somehting serious.
Wow, hard way to learn a lesson! I'm guessing the message here is appreciate the time you have? On a side note, reminds me of the movie "The Fountain".
As both a fellow writer and scientist I will give you my thoughts.
Being a scientist himself he raises his own intelligence for the betterment of humanity. After entering the Time Void and becoming unable to eat and possible sleep for 5 years he may have a few angry opinions about what he did. However he wouldn't go as far as to blaming others for his own curiosity. Having the drawing power with the marker the logical standpoint would to recall the information he saw on the board in an attempt to understand the device. Something which would take years to understand anyways but doable if he really wanted to leave.
The more important factors of this story are the implications and effect of the device missing. You don't just "be" a scientist. You have an idea, a group funds you to make that idea possible based on the values of science. Over the course of the 5 years that group would have noticed the scientist and the device missing thus linking the two. The fact that 5 years past in-story and that building was clean and with power means the group has considerable finances to make the other scientist rebuild the device. Though with the chalkboard erased and him running out, would be implying the control of time is too great for anyone to have. However leaving the device on the table is either a careless mistake by him or he was running to get the higher ups to look at his research. Either way they were close to perfecting the technology with or without that scientist. Which means with-in those 5 years in the Time Void he would have met others at some point.(Given that there is only one general space for all time travelers to interact in while traveling between destinations)
I would suggest continuing the storyline though an enemies eyes. Portraying the scientist as a villain trying to corrupt time by bringing back his lost love. (Which also could be put under the impression that the group saved her to use as a bargaining chip in order to get back the device if he ever returned.) I digress.
It has potential...
Deep message badly delivered. Feels pretentious.
