0.2 is out!
Here are the most important changes:
Some tweaks to the combo system:

• Holding a bomb pauses your combo’s timer.
• The animation played while opening a locked door now pauses your combo’s timer.
• Entering a door pauses your combo’s timer.
  Some tweaks to gameplay, such as:
  The TV showing a new S rank screen when, well, there is the S rank!
  Cancelling a wall climb is now disabled like it would in final game (to help with people who press the key before pressing jump).
  Removed the, albeit short but annoying superjump delay (should help with TASes too!).

Note to snoopers: if you want to edit this version, check gml_Object_obj_tv_Create_0 and change the “global.snoopmode = 0” to “global.snoopmode = 1” to have some more debug info. Currently only shows combo time.
