Hi, since the last post, I have followed a few more points from the changelog for the v0.3.0 update!
List of fixes:
1) Fixed a bug due to which the next level was not saved when the player clicks exit or restart in the window of the end of the current level.
2) Fixed a bug with opening the pause menu when the player presses Esc in the play window.
3) Increased camera speed. Now going downstairs, the player will see everything happening there in advance.
All this will be included in the v0.3.0 update!
