Alright. I finished the first act. On the whole, I think it's a bit of a low quality remake, and I'm not sure it really justifies $30. The fact that the mobile versions are $20 is a telling sign.
I love the fact that they adhered to the movement of the original for the most part. The Master's moveset is expanded from the original, and the combos are really good. It really feels like a GBA/DS era Castlevania game in this respect. You're still committed to jumps when you make them, and you have to plan a bit carefully. On normal mode, the game seemed a bit easy until I got to the boss. I died once there, but I did appreciate that the boss wasn't exactly the same pattern as the original, while still maintaining the same moves for the most part.
Overall, I think the gameplay is pretty solid.
However WHAT IN THE WORLD is going on with the graphics and performance? This does not perform well on Switch in handheld mode at all, and parts of it look downright ugly. The animations appear to be very choppy at times, and I'm extremely disappointed here. The weird 3D protagonist is odd too, and I'm not a big fan of it. The presentation leaves a bit to be desired, and it lacks that SNES era Quintet charm. Which is not a good thing considering this is a beloved cult classic.
EDIT: Performance is much better docked on the Switch, and from what I understand, the PS4 version has good performance too. Still, something to keep in mind.
The remixed music is fantastic, no complaints there.
I would say hold off for a price drop, as this is not a very high quality game in the presentation department. I don't understand how it was acceptable to release this as is, but the fact that there were mobile ports has me asking questions. I don't regret my purchase, but the game would have had to be absolute crap for me to regret it. Your mileage may vary.
Gonna play this the rest of the night. I'm onto the simulation portion now.
