The level is visually more complete, including lighting. However, personally, I didn't enjoy the aspect of memorization paired with unforgiving one-hit-kill obstacles. Even when the crystals are visible, platforming is extremely tight at times and hurtboxes don't match up with graphics, and the tight platforming is even more pronounced during the invisible parts. Having to repeat levels to refresh obstacle placement was also tedious - it would have been better to be able to return to the end of the level.
While unforgiving games like this may not be my favorite, it is still a good simple demo project in my opinion. The memorization aspects could be utilized in a more enjoyable way in another projet - perhaps with more forgiving obstacles, for example.
