The artifacts of marvelous birds - Bowser's Castle

• The artifacts of marve...
The time has finally come to upload the last level of this game, Bowser's Castle.
As you might expect, this is the longest and most possibly hardest level of this game, and also which I have ever created.
With this level complete, I believe I made use of every single sprite there is in SMW (except for some generators that just vary a bit, some platform sprites and obviously the original bosses. Also Yoshis since they are not in this game. I may or may not lie to you about this).
Room 1 introduces the creating/eating block snake that follows the original castle #7 path. I also made use of the diagonal Podoboos for the first time.
Room 2 has the first checkpoint and introduces Boss Bass from SMB3, unable to be killed, as well as football chucks which haven't been used bfeore. This uses the layer 2 translucent level mode, which works even with message boxes. Thanks to some patches and help which I forgot currently. This subroom is possibly the hardest because slippery+boss bass+footballs+spikes is just cruel.
Room 3 has the second checkpoint and lets you decide between a door to Room 4 or 5.
Room 4 & 5 makes use of scrolling sprites, SMB firebars, spike balls for the first time, and a fish generator in room 6. Love the Pokémon TCG reference as well, you are most welcome.
Room 7 leads to the last checkpoint and the boss fight with a Mega Mole, which you can see for the first time, but has actually been made use of before, and a custom Floating skulls sprite.
The music might be subject to change.
I decided to upload the Bowser fight in a second video, because a) I died in this attempt anyway and b) because it contains end game spoilers. If you want to see it, follow this link:
• The artifacts of marve...
I needed 100-150 attempts to get to the Bowser fight without dying, so yes. This is hard, but the checkpoints help you out.
What do you think?
PS: There will be one final video of the credits level. Soon™
PPS: Feel free to compare this to Bowser's castle from my old hack "Mario's World Tour" 17 years ago xD

Time limit 800 sec !

[@shffler1337]

Well yeah, the time limit is somewhat infeasible here, since for such a long level, you can't specify a proper limit from start to finish that makes any sense. When a player dies after a obtaining a checkpoint, the time limit is set anew for this room. For example. you get a new time limit in the room with the first and second checkpoint (at 4:44), and then also for Bowser's fight itself. Thus, the initial 800 seconds are not even enough in total to complete this castle.

Okay seriously, I'm impressed at your dedication to finishing the hack after so long. Also nice to see the bowser castle set that moltz made being used

@@SF-TDW Thank you. Yup I delved through every Bowser castle tileset on SMWC and this one I liked the most. I was too lazy to draw my own tileset although I do have some custom stuff in there.
