looks like in update 14 there will be a new save system (guessing making the older save files useless), is it the last one?
by the dev's own projections, there's still about 10 months (5 updates) until the game is finished. also, the new save system should keep progress from v0.13... but if it doesn't, someone here will probably be upload a full save soon anyways
Past saves should still work on the transition to the new version.
There will not be 5 more builds though. There will only be 1 more for Patreon after this. v0.15 is projected to launch around August 1st, then the final level should be around October 1st(This last level will likely not be released until launch). The remaining 6 months is for endings, polish, implementing the last of the VA, UI, remaining features, and after that, getting things approved for launch.
It's crazy how hard it is to figure out what the dev expects you to do in order to get these chips. Something as simple as "Kill all of X Enemy" is a trial by fire because for all you know, the enemy type you're trying to do a successful genocide on is the correct one and there's just a blink and you'll miss it moment where that enemy shows up or is just straight up hidden that you're just somehow failing to notice every time.
The hints are quite obscure at first, though some are fairly simple, once you get 5, you will unlock "Expanded Hints" which are much are much more detailed.
This is the first implementation of it though, so there may be changes depending on feedback.
Wtf, the game now has no saves? I exited the game, but the continue button is not active.
v0.14 had a bugged "Continue" and "Settings" button. I did a hotfix shortly after, which I'm assuming you do not currently have. I would say don't worry too much atm, though. Your data was probably saved, just not able to be loaded. Whenever you get access to the hotfixed version (v0.14.1), you should be able to load it as long as you haven't tried to start a new game since then...
