Dive was visually pleasing to the eye.
A couple of puzzles towards the end were nice and tough but not unfair. It's quite a short game, can be beaten under 40 mins.
Some hit detection feedback would be appreciated, When you die or just fall on spikes it resets the level with no SFX's and more background music would be a must but it's understandable if that would cost too more for a short game like this.
Over all I liked the mechanics but it's length and how it ended felt a bit abrupt like it was more of a prototype than a product. Though I would like to see some more set in the Dive world with more polish to it.
