Was a big fan of the original game and this is also great, gives me another excuse to play it all over the game. Loving the change to the bonus screens to add bosses, and looking forward to see the new levels!
I did run into one bug, i somehow managed to have permanant boots powerup even after death, although it reset after changing level. I didn't manage to capture exactly how it happened, but i think i died almost directly after picking up the powerup when it happened.
Also i had a question about level 16, back in the original Spectrum version you were always guaranteed to get some sort of powerup to get past the Snake to get the top left treasure, but in this version it seems more random, several times i have had to sacrifice a life to complete the level because i would only get a boot or shovel powerup. Is this intentional or am i missing something?
