This game is great. Thoroughly enjoyed it. I liked the way you presented the story in a natural way and didn't just info dump the player at the start or just straight up tell them what was happening. What you managed to make with the RTP is very impressive. Overall it seems you were going for a more serious and mysterious tone for the game. As such, I thought that the joke about the doctor never using a cellphone again was a bit out of place. It completely shifted the tone from mystery to comedy and I couldn't tell if I was still supposed to be taking the game's world seriously anymore.
Also, I didn't have any lag in my playthrough (some other players have mentioned that they have). But my PC is fairly decent so maybe that had something to do with it. I wish there was more of an ending to the game but I guess that will be in the full version. Regardless, I gave you max marks in all categories despite any of these small critiques I could give.
