understandable, I know there was some annoying kinks with the buttons (so no, it wasn't you being dumb :3 ) … I actually redid the buttons to work correctly (on the latest patch)… the issue came from the fact that the souls had multiple colliders and the button script was super rushed and basically only worked one way (hence why the ending didn't have buttons resetting). In terms of the un-pressed button towards the end, I'm unsure whether its a bug or part of the puzzle … I know that 2 of the platforms actually disable a platform while enabling another... I cant really explain it numerically but the puzzle always leads to the final button being the first active platform... in other words, the middle platform closest to the previous section is the final button that needs pressing. all in all, I'm glad you enjoyed the aesthetic and I will definitely be making a more clearer teaching flow through a more structured but entertaining tutorial. If you are interested in trying the game again, feel free to check out the updated version (currently 1.4d) or keep a look out for the 2.0 which I am slowly but surely working on :)
