you know I can agree with you, but I can't seem to get the test levels unlocked in this version, maybe he got confused with the itch.io build and the steam build, so he put the steam demo build here and on steam (steam version doesn't have test levels). R.I.P. test levels
You are right about the version, the current itch.io one is the same one from steam. I did that to unify both for the new trailer. The test levels are done for testing mostly, they are very rought around the edges and I don't want people to think the final levels will be that unpolished. I do update with test levels every now and then if you want to play them.
Also thanks for playing!
