Played the game a bit last night. Here are my impressions:
- Some SFX are definitely worse than the originals, and some others are way better, like really creepy SFX that help the overall feeling of dread.
- Isaac's voice is... unsettling.
- Long rooms are awesome, chock full of enemies. I kinda wish the loot for those levels was a bit more than just the random key or bomb, but it's not a big deal, rooms are still fun.
- I haven't met any new boss yet, but variations from Larry Jr. and some other. Very cool additions.
- Got Little Brimstone on the second playthrough, unfortunately I was just about to die so I couldn't enjoy the bugger, but the look on my face when he gave the first shot!
- Movement is pretty much the same as the original. I haven't seen any drastic change and felt right at home. The day before yesterday I was playing it on PC, yesterday I got it for PS4, and it was like playing the same game, movement-wise.
- Graphics are great as well, but I much preferred the hand drawn style of the first one. Still looks amazing, but it can get hard as fuck to see the flies on dark rooms.
- Full screen Isaac is definitely the best Isaac.
