Tip: Switch palace switches normally disappear if you replay the level. However, if you insert them as direct Map16 and use the hex edit at $00EEB2 in the ROM map, you can replay the level without a problem.
Kruela Mario 2 is a glitch-puzzle-hack featuring 24 levels with 29 exits. As the name implies, it is the sequel to Kruela Mario (and thus, this hack is completely in Esperanto!) but the level design has changed quite a bit: In contrast to the first hack, this is almost entirely devoid of kaizo design and instead focuses on being a puzzle hack. This however does not mean that the hack is easy and I strongly suggest the use of savestates, slowdown and a lua script as the glitches required in this hack are rather technical and sometimes difficult to execute. Of course, this presumes that you already figured out what to do, which (hopefully) is harder than executing the solution in most cases.
Kruela Mario 2 features an open overworld and every level is accessible from the start. This was done to prevent the player from getting stuck early on and never having a chance to see the later levels. However, the levels are still roughly ordered by difficulty and you should try them left-to-right, top-to-bottom. The earlier levels are fairly easy (for the genre) and some of them are completely trivial provided that you know the required glitch but I hope that the later levels are sufficiently difficult to accomodate for this. Another thing that drastically increases while you go along is the level length: While some of the earlier levels span less than 5 screens, the final levels are much longer.
As a lot of levels in this hack are reliant on "difficulty by obscurity", this hack is not for you if you don't know a lot of glitches and/or are not willing to look up any of them. To give a more concrete example: The stun glitch is used a fair amount in this hack, so if you don't know what that is... you might want to play a different hack.
This hack was originally released during C3 Summer 2020. A changelog with all changes to the original release version is included in the download. SRAM files should be compatible between versions.
Kruela Mario 2 is just an extremely well made glitch puzzle hack. The hack features a variety of glitches, quite a few of which haven't been used before. It has a nice difficulty curve, with the world 4 levels being some of the best and most difficult glitch puzzles I ever played. While there are some breaks (as in any glitch puzzle), coming up with one still takes a considerable amount of time and thinking. The levels have nice palettes and fitting music and the vanilla aesthetics make it easy to figure out which tile does what.
