This is the second part of V2.3, and nothing much was added. First part: https://seenwonderalex.itch.io/baldis-basics-tud/devlog/519973/v229-partial-upda...

Here are the changes:

• ADDED CHALLENGE MODES (Speedy and stealthy), the last challenge mode will be held off to V3. 
• Fixed an issue on some mobile devices not being able to touch the 3D movement toggle.
• Fixed an issue where Chalkles and The Test couldn't be turned off on custom settings.
• (From the first partial update) Fixed an issue where walking to a swinging door on multiplayer would crash on the browser.
• (From the first partial update) Fixed an issue where you get stuck in the jumpscare screen on multiplayer.
• (From the first partial update) The health system was overhauled. Fall damage has increased. Teleporting from the second floor by the principal will make you take severe side-effect damage. The third floor will make you lose. You'll take damage if you're late to Mrs. Pomp's class.
• Fixed an issue where new players couldn't play any mode.
