this is honestly one of the projects im most excited to see, i keep coming back to check if theres been any announcement or update. awesome to see you are doing a dev log now, the game honestly looks great, and i cannot wait to see it fully. i find it infinitely funny that an indie dev may give us a genuinely great doctor who game before the bbc do. If i had to guess about the villains of levels, level 1 is obvious since its in the title, an I assume Red planet rescue is probably going to be ice warriors (could be the flood probably not) and would assume level 3 is weeping angels. if i had to make a guess on level 4, id say probably something to do with daleks given that its a doctor who game so you sort of have to include daleks somewhere, with level 5 maybe being multiple villains if its a deathzone type thing, what with the timescoop, or saving daleks till last.
cannot wait to see more of this, keep up the good work, it looks fantastic!
