I'll be honest, after episode 3 I was starting to get a little bored cause the story was moving slowly, the gameplay was a little boring, and I felt like the decisions you make weren't real significant in that episode. Plus there were several glitches with the camera getting stuck that caused me to have to go back to the last save point several times.
But then I finally played episode 4 last night. Wow! The storytelling was so much better, I was on the edge of me seat the entire episode and it never got even close to boring. Gameplay was improved, less glitches this time, and you finally see the results from a lot of your decisions. Also felt creeped out during a lot of the episode cause parts of it were so scary. The sewer parts reminded me of Resident Evil!
Great job, TellTale, Episode 4 was amazing and a great improvement from the last few episodes. Looking forward to episode 5!
