Hi Pedro, I enjoyed your game. Frankly speaking, I enjoyed your game a bit too much I guess. After having played 10 hours plus I even decided to make a video in speedrunning fashion.
Lets talk about your game:
First of all I want to address that you nailed the theme, in my opinion, of this Ludum Dare. Having a stunmechanic that becomes worse the more often you got hit is very fitting. The second theme based mechanic is losing time faster after you drank from the eldritch blood. You could also go so far and tie your time mechanic to a H.P. Lovecraft theme. For instance, every time you drink from the blood you become a little bit more nervous and your insanity meter depletes therfore a bit faster or some sort of H.P. Lovecraft horror theme (because you know everyone in a H.P. Lovecraft story becomes mad a certain point in that story).
Secondly I want to talk about your enemy design. What was outstanding is the fact that the enemies are designed orthogonaly, meaning that they have different attributes. You have the EyeOrbs that avoid you and try to snipe you (trust me they will snipe you) and on the other hand you have the DeepOnes. The DeepOnes are incontrast to the EyeOrbs very slow, but pursue you and in contrast to that you have the fast moving fast attacking Cultists. There also enemies that are almost completly immobile but can take a lot of hits and shoot with a spreed shot pattern to compensate for their immobility.
The next topic is the level design. A bit simple. However the Levels you created did their job very good. At a certain point in my WR run you can see that used a corner to slow down two Cultists. Otherwise killing two agroed Cultists would have been a difficult task. I realy appreciated the H.P. Lovecraft inspired atmosphere of To The Depths. Being a Lovecraft fan I realy enjoid the crawl through the ruins.
The last point is the gameplay. Overall the feel was very good and it almost felt if the game was in a refined state. If you time your attacks on the DeepOnes correctly you can stunlock them. I were also able to stunlock the Boss (not sure if it was intended). It was almost like I was dancing with the Yogs. The Yogs were especially hard after I managed to reach them for the first couple of times. Until I noticed that a Yog will immediatly do a slash attack after you attacked it and you only had to repeat that until it was dead (repeating that hit and evade tactic is what I mean when saying "it almost felt like dancing"). I also used the Shoggoth to my advantage, because the shots of the Shoggoths can also open the doors. Those Shoggoth shots could also open doors that are not on screen which is especially nice in a speedrunning context.
Overall the experience with To The Depths was great. I had a blast playing your game and it also inspired me to make my own To The Depths (and I am definitely waiting for updates on this game^^).
Bug: not sure with this one, but it seems that the reaction time of the cultists becomes longer the longer the game is running. Could be a problem with the engine?
