I released v0.4.0 and v0.4.1 BETA. You can find a list of what'd been changed below, aswell as what's planned for future updates:
v0.4.0 BETA
+Added the first Set of World B
-World B starts locked, but can be unlocked (And will already be unlocked if you beat World A)
+Random glitch effects appear past World A
+Clicking an object with the select tool will select it without having to draw a box around it
+Select tool + ENTER and Select tool + DEL now works with Undo-ing
-Pressing escape while in end portal no longer breaks things
v0.4.1 BETA
+Added News to the Level editor
+Added Help to the Level Editor
What's planned for the next release?
- A News tab on the main menu which shows Steam News information
- A showcase of all levels submitted to the current weekly challenge (if there is one)
- When you upload a level it will ask you if your level is meant for the weekly challenge. If you say yes, your level has successfully been submitted! But if you say no, it's still going to upload just the same, but will not be submitted to the weekly challenge.
