By: Bock

*EDIT* Patched version 0.91 fixes the problem with switches.
"EDIT" Patched version 0.92 fixed starting level and version number. Please re-download if you tried an older version.

Aargh, it's back! To torture me again!

Is anyone else having trouble flipping the switches?

Yes, in the second level :) I think I saw a gate opening one pixel, but then it closed again. I hope Omar can fix that before the voting. It would be annoying to get bad votes because of a little bug like that.

OUCH
I am gonna fix it immediately

I uploaded a fixed 0.91 version.

There was a terrible bug I introduced on an another object used in the last level, it was doing a RET and forgetting a POP before. It is total luck that the game could even run. Anyway it is fixed now.

I began to think that fusion is doing something wrong in SMS that switch in 2nd stage would not work :P
This is so fun, best coding part entry :D

Always use indentation to signify that things have been pushed :)

Hmm, I think I see some problems:

- Meka can't load the zip, same problem as my first entry - the ROM ahs to be the first entry, remove and re-add the readme to fix
- The SDSC version number wasn't updated
- It starts on level 2 instead of the title screen! Debugging hack left in?
- I still can't walk through the door after it opened!
- I jumped into a yellow flashing "rope" as it appeared and KunKun got stopped NOT ON A MULTIPLE OF 8 PIXELS which is obviously against the natural order of the world.

When I write a PUSH xx line, I'll immediately write a POP xx aswell, otherwise it's certain that things get missed and eventually crash (in case of MD Z80 side, your code is in RAM and eventually stack will wipe things out).

The SVN repository with source code is publicly accessible here:

Don't look before finishing the game of course :)

You forgot to update the version number at the top of the readme :D
This game is so hard... Is there someone really good in this game who can post a playthrough video?

When I noticed I couldn't get through the doors I used the ram editor to beam myself to different places. I miss a fun reaction when falling directly onto the princess. =)

Bad boy Martin ! The game is hard, it is meant to be this way. Try to enjoy it without cheating for a bit.

Now, I'm in level 5 without any beaming. But I don't have the patience to do it without save-states.
Edit: I beat level 5. And level 2 without cheating :)

Addicting and looks fantastic! I reckon it would have been one of the great SMS titles if it were a commercial release back in the day.

Some facts:

- I started start on March 18 and skipped several days of work due to other obligations. Figured out I had not much time so after some brainstorming I decided to re-use the original KK&KK as a base. I hope this is not a disappointment.

- I think I spent about 30 hours on it overally. Not really a good time for me since I had deadline on two other games (!) on the same time. Probably half of time went into designing levels. Levels 2-5 probably took about 4 hours each to design. Most of them were completely done in an art package, and only when completed ported to the game and a few flaws fixed. Very few actual in-game iterations. It was rather tiring but exciting for the mind to design the levels without playing trying to maintain all paths and possibilities in my mind.

- I improved the data pipeline and level editing process to be much easier than in the previous game.

- Needless to say I hoped to have more levels, but time was too tight. With the new features there's probably many more nice levels to make. Maybe I can add another level for version 1.0. I also hoped to include as a bonus an hardened level 3 from the original but it was unaffordable luxury at this point.

- Technically nothing special. It is a game built around technical and design simplicity which as a envisionned it would allow me to do something (as opposed to solving more complex technical problems and not getting a game done). So the design was made to dodge as many problems as possible. But that is old news.

I wonder if anyone actually started his compo a month in advance ;)

I may as well join in. I took 4.5 days holiday to work on my entry. Overall I probably spent about 35-40 hours on it. It became playable after about 25 hours, but lacking most features; collision detection (with lots of bugs), score calculation and interrupt routine optimisation were the things that took the most time.
