This is quite a creative and interesting program, IMO, and I’m testing it right now.
One recommendation:
When CashKeep is activated, I recommend warping the player ONCE to 2, 2. Currently, the program warps you to 2, 2 for an indefinite number of times, so if you have not completed the level, you can never get out again until you’ve clicked ‘End Keep’ and jjnowall/jjfly your way out of there. This can also be a big problem if you do not click ‘End Keep’ before the next level loads, since you’ll just warp immeditely to 2, 2 and get stuck there…
Perhaps you could reupload an updated version? ;-)
EDIT: In fact, the program warps you so quickly to 2, 2 that it doesn’t even allow you to fall down into the Exit event. The player must click ‘End Keep’, then quickly ‘Start Keep’, and finally ‘End Keep’ again.
EDIT 2: The program seems fully functional in TSF. The method I had to use was different from the one Cash Keep told me to use, but it still works twice, and I was impressed enough (and kinda forced) to run through all 3 Cash Keep levels twice. Even though this is still v0.1, it works well enough and people can already start making levels with it. I will rate this when a newer version comes out, however.
…and I just found out you can’t recommend an upload without rating it. Well, I don’t care! DOWNLOAD RECOMMENDATION!
EDIT 3: Well, the program is now more easier to use, and works just as well in 1.23, but things have taken a turn for the worse, as the program sets singleplayer to co-op, meaning that you can no longer use any cheats, and you will not be taken to the Game Over screen when you run out of lives. Instead, you will have no choice but to start the levels from the very beginning, rather than from the level you died in, which is a problem for big level packs.
