Crash Bandicoot - Test room
This is a room internally referred to as "level1" in the game's code. The only way to access it is by hacking the prototype.
This level was frequently used and modified by Andy Gavin to test some features in the game before implementing them into proper levels. In Andy's words:
It was always very useful to have a level that was super small (hence I could process it in 3 minutes instead of 6 hours). I'd just stick whatever creatures I was programming there first and do all the programming I could on them BEFORE putting them in a real level.
By the looks of it, Andy was testing the jumping spider and beaker assistant when this prototype was compiled.
