Very castlevania-esque.
The map was interesting to explore, but other than that, a lot of things felt like they need a lot more polish.
The wall jump was a bit uncomfortable to use on keyboard, and the lack of any grace period before beginning to slide, combined with the relatively fast sliding speed made it a bit frustrating.
Enemies - other than the boss guarding an upgrade - don't seem to attack or do any contact damage so I can't really say anything about the combat.
The train taking you to another section was surprising, but fun. The ruined tower was fun to explore, but the intended path, and what constitutes as a platform was very much a guesswork.
