The green switch block bug should now be gone. Alongside that I managed to figure out a semi-fix for the yellow teleporter alt+tab issue, as well as fix some small issues related to the game timer.
So yeah. I had known about the switch bug for some time, but had assumed it to be a rare problem due to me not having touched that bit of the code since release. I filed it away as a "fix this in a future bugfix patch", but only now noticed how common it was. It's embarrassing that just by looking at the Steam forums more often I would've noticed the seriousness of the bug, and I deeply apologize for the delay on this.
The past year has been extremely busy, not only because of Noita; since I could rely on the aforementioned assumption that the green switch bug is fairly rare, I allocated my energy on other things during 2019. Obviously being busy doesn't really justify the game being broken, especially since it was part of the Nolla Games bundle and all, and as it was good to see that some had gotten refunds even beyond the 2-hour playtime limit due to this problem.
Luckily for ESA (and me), 2020 is looking to allow me a bit more time, and I'll be allocating part of that to maintaining ESA again. The biggest thing I'd like to fix still is the gamepad support; the only way to help this is to rewrite the entire gamepad code, which feels terrifying, but in the end I doubt it'd take more than a couple days of intensive testing and tweaking to get going. Sadly, this fix probably wouldn't help with the lack of gamepad support on Mac; I'd have to look for other solutions there.
All in all, apologies again for letting the problem exist for so long; it should be gone now and I'll be monitoring the community forums more closely again now that I have the time. Thank you for your support.
