Snowy treasure hunter 3 level 73 can anyone tell me how to do it. Thank…

I have tried everything I can think of..and can NOT p level 73. The pre picture shows what looks like a key on the lower bottom left side.Yet no key...nor do I see any reason a key would be needed. There are not enough pumpkins to blow up all vampires. I always end up with all slots filled with monsters exscept last slot...and no way to get to the exit since slot is empty! I sure hope someone will end this mystery...HELP!!!!!

The easiest way to get out of here and it's cheating! Once you are in the level, type in the words "LETMEOUT" These cheat codes are case sensitive! So type them as you see them! Now move fast and get the key. The rest is up to you. Also, if you are still having problems, not fast enough. Then type in the words "SUPERSNOWY" and you will be able to walk right through all the monsters. This is real cheating and does take away the fun. But it works!
