I played this for about 40min. I had to check about every processor to find the one i was looking for. How they are laid out needs to be supplied to the player in some way, on the map or in the manual. I completed it and tried to receive a new one in the terminal, but there were none. I couldn't exit for the day, so I just stepped around until the timer reached 0, but I still couldn't exit. So I gave up at that point.
Tilesize is small, but the biggest issue for me was that I had to use the clickable arrows often to realign myself on the grid. Those makes you step one step at a time, but the WS key inputs steps two steps and sometimes 3.
The core idea is solid and could make for a great game. I'm rarely a fan of RPG maker but this is one of the best implementation/use of it Ive seen so far.
