Keyboard didnt work but game ran fine in the link provided. Proper reminds of of old school NES Games as mentioned in your description :). I only have vague memories of Lode Runner but seems the same principal. Get past the bad guys to collect the items. Having to find the exit at the end is an interesting touch to. Also, quite a few mechanics in place here that got me thinking "Wish knew how to do this" but rather than ask for detailed explanations I will just keep on learning and try to look it all up myself.
