Yeah having limited assets was part of the problem of that since i wanted everything to be black and white and there is just one door sprite (and no buttons sprites, that was a workaround haha) but after the voting period ill probably think of a solution with sounds or something of the sorts :)

I see. I understand.
Well, one thing I could suggest if you were to develop the game with the same restrictions is use the lock door and key instead of the regular door and button for the one time door opening part. (I used the same asset pack, so I did see two types of locked doors)
One might think it's strange that a heart could collect a key and automatically open the door. But hey, if the character can teleport to the heart's position, surely anything is possible.
This is just a thought, though. Still a lovely game. (No pun-intended ... I think)
