to be fair... the bar of quality for AAA games nowadays isnt that high... there are a few AAA that actually feel like AAA but the rest not really... so dont sell yourself short... i was fully expecting the game to be abandoned at this point... so i am glad that there is still some air in the lungs on this one... ill be fully expecting a much better game than what it is currently

he simply announced the Release dates on Itch ... besides he clearly stated 

[0.7] - Changelog & Release Dates

and on the release dates it says "Tier" which makes it obvious (i think) that it isnt Itch because i dont think Itch has any form of Monthly Payment for there to be "Tiers" ... if u pay for the game here then you will only get the 0.6 version as stated... if u want to buy the 0.7 on Itch then u will need to wait till April 16 for the Public Release 

what is there to be confused about? do u know how to read? 

Release dates:

• Demon Lord Tier - March 21 - 03:00 PM (UTC)
• God Tier - March 23 - 03:00 PM (UTC)
• Eternumite Tier - March 29 - 03:00 PM (UTC)
• Master Tier - April 4 - 03:00 PM (UTC)
• Supporter Tier - April 10 - 03:00 PM (UTC)
• Public Release - April 16 - 03:00 PM (UTC)

i think this is pretty self explanatory ... the game will be in ITCH in April 16
