The graphics are nice. Simple, but immersive. The installation process was kind of weird though, windows 10 was not trusting the file... Couldn't you export to web? Its much easier that way...
The idea was interesting, fun and fast dungeons... It looks like it could become very interesting with some cross-run progressions...
But it felt too harsh... You enter the room and a lot of things are happening, you need a few seconds to understand what's going on... sometimes the enemies are almost killing you when you understand the room layout.
The 10 seconds countdown is working properly? I didn't understand what it represented... the room wasn't lost when the time reached 0 and I was able to get the key even after the time ended.
