Added platforms Windows, Android. Fixed bugs with web version:

1. Narwhals would almost always spawn on top of the player and immediately kill them, making the game unplayable in most scenarios

2. The version of Unity used had an issue (https://issuetracker.unity3d.com/issues/audio-no-longer-plays-in-build) that caused audio to not play with web exports. Updated version of Unity and re-exported. (not technically gamebreaking, but the fix was a side-effect of having already updated my unity version)
