Seems pretty cool, I think you did a great job at translating the look and feel to PS1 style graphics. But it's really hard for me to play because movement inputs seem weirdly unresponsive. Sometimes I'll press a direction and it'll take more than a full second for Isaac to decide he feels like walking. Not sure if this is just a bug on my end.
Having the same movement issue. Just stuck in the elevator forever, with gamepad and keyboard movement controls being unresponsive. Based on some videos I'm seeing, maybe some audio was supposed to trigger? On my machine it's not triggering, so if you're waiting to unlock movement when it completes, that's likely the issue.
I was one of the level designers on Dead Space back in 2009. Glad you liked it enough to build this!
