Really nice variety of items and puzzles. The gameplay is simple but well executed. Realy liked how most of the time there isn't an obvious choice when picking a new item.
Navigation is quite clunky however. The large fov combined with the repeating texture make movement nauseating at times. Missing the options to move back or strafe was also a pretty hard downside.
Nice work overall, nice way to treat the theme while being very faithful to the old crawlers.
