Huh. I'm in the middle of doing updates, but I wouldn't mind making a GLES2 build, to see if that solves the issue.
I'll post an experimental build with GLES2 here next week.
It worked! Thank you very much, the game was great :D I'll definitely spread the word about this trick, in case some other devs are willing to try it.
Some curious things I noticed (no problem to speak off): the 20SM.exe I initially downloaded is 153 650 kb whereas both of the current downloads are only 71 354 kb. Did you change it at some point or did I download something weird? I'll note that this new (?) version doesn't work either, but it does manage to enter fullscreen, whereas the former only became a borderless window stuck to the upper left corner.
I also found a minor bug: if I return to the menu after starting (not resuming) a new game, the slot selection maze's dot will not move until I relaunch the game.
I'm glad you enjoyed it!
As for the size of the game, I did some optimization on the game's files a while back (mostly switching audio from .wav to .ogg, also deleting some redundant files) and managed to halve the size of the game. That's why it went from 153MB to 71MB!
And thanks for letting me know about that bug. I will add it to my list!
OK I just found a trick that would've worked even before, and indeed has allowed me most of those previously-bugged Godot games (only the ones that don't need GLES3-specific stuff, I guess): I type "cmd" in the game's address bar, then in the console I type (in this case) "20SM.exe --video-driver GLES2" That's it LMAO *facepalm*
I also forgot to compliment your usage of blackbird song as background noise.
Oh definitely, but I wish I'd known about such a simple trick before. I just kind of stumbled upon it: I'd read that people who had the blank screen problem with the Godot software-/editor-itself solved it this way, and I suddenly thought of trying it on those games, but then I didn't even know how to run them (or anything) from the console! I wasn't even sure whether that was possible (lol), I just googled stuff until I saw the trick of writing "cmd" in the explorer's address bar. Anyways, I'll just spread that trick around when relevant.
