The only possible instance I can think of that may not be covered, would be the apple on the floor in the barn. with the apples in your inventory... the singular apple is always deleted whenever it comes into contact with the apples (i.e. when it's picked up). I can easily sort out that, if that's the case... I don't think many people will put themselves in that situation, anyway.
The game was just a quick entry into the jam... not really a proper adventure... I had it done on the first day. (Although I did go back to it and add a couple of extra puzzles... and a lot more responses that probably nobody will ever see!)
I've just been waiting on the graphics. What I've already got for the game are excellent, but they won't all be done in time for the end of the jam, which is why this version (with my very quickly produced art) has been released. The 'old' version will always be available from my website, but the proper graphics are much (much) better. So I do hope they will eventually make it into the game.
