Using this theory i have a proposal for an update:
-I have counted 14 cassete tapes
-So I propose that in the next update, 2 of the tapes will always be in level 0
-4 of them will always be found in level 1
-5 of them will always be found in the intermission
-another 2 will always befound in level 2
-and the last one will always be found in level 3
With this feature, another feature will be added to go with the first feature. The second feature will stop you from going to the next level without finding the cassete tapes for the current level. For example, you will not be able to go to level 1 without having all of the cassete tapes from level 0.
