Thanks! It's still my favorite O2 homebrew since Mr. Roboto. Would be nice though if the bugs got cleaned up and there was a ROM release with the fixes. Can even more RAM be used with bank switching in a cart or ROM file to be used with O2EM?
Thank you Doug!
I depleted all 8kb of memory and still had to shrink the original program to fit all the code of the new game. If there was additional space I would put a soundtrack in the introduction of each floor that I developed, and still on the top floor there would be a challenge aside to get an extra bonus and start a new tower with a temporary shield.
