I’m soooo sorry, I introduced a typo the id ends with 775 not 557 (I mentioned it on the game page). You got it right, I just messed up, but it was the last Puzzle I managed to include anyway so you basically beat the game :P
I know about the bugs with the columns, it’s because i didn’t quite finish the tile set. The columns are not a thick as usual wall tiles, that’s why you can walk through there. (You can even break into the final room like that :O)
I’m also aware of the issue with the tooltips, I put explicit logic in to prevent this issue (opening and closing the inventory again should help), but somehow it didn’t work (i guess some timing is off). Btw. you can also use the arrow keys to choose the items from the inventory and confirm with enter.
I have to admit, i didn’t think about the controls when designing the game, I just went with something easy to remember (i = Inventory) but i agree that it’s kind a clunky and doesn’t play that well. But I already have a better way to handle this in mind :) (stay tuned)
I’m just glad that the whole thing wasn’t too complicated and you were able to figure it out.
