Ah... Let's see, this is something of quandary for judging. As an EXE, it makes several improvements on OpenGL, adds in some new controls, and tweaks the physics. However, several forced changes in existing objects and object sprites as well as some textures, the HUD(lack of lives, lack of time, "gems" instead of rings, different), and the removal of the "god" console command prevent it from being an effective or worthwhile content platform, especially if any of these things were to be set to change in the future. In addition, the lighting seems skewed towards the brighter levels once seen in 1.09. Additionally, software mode is not present, though it is acknowledged that this is a conscious decision, for the purposes of the levels being designed.
The 1 SP level in question is a NiGHTs map, but the track is broken, and does not remotely follow the setup, and indeed boxes you in on one small side of the map. Given this fact, if it were a level placed in submissions by itself, I would have sent it to trash.
The Match level, while needing many more rings(particularly in the higher floors in the middle) would be passed into releases if presented separately.
All the forced changes make this very hostile towards wad computability, and development for the EXE itself. As an EXE release alone, it would likely be rejected on the grounds that it is not currently at the point at which development on the new platform would be feasible. Easy fixes on this end include making the sprite/object changes held in a separate wad, which can be added at launch to "restore" the state of the game to a point resembling what it is now; otherwise, sprites and objects would be as they are in normal SRB2, sans new physics(in total, the sprite replacements, SOC changes, and HUD changes would be in a wad; particle effects are negligible). This would allow for compatibility with existing wads, which is something that people who download this would be looking forward to; trying out their existing levels with the new EXE changes. This is the preferable way this could be prepared for releases.
However, a more urgent modification required for the feasibility of the EXE in it's own right is the restoration of the TIME entry in the HUD, and lives.
However, as an EXE designed solely to support a levelpack you are designing for it, it could be passed once the NiGHTs level is fixed, though I wouldn't suggest doing this alone, for the reason that this would limit the EXE's lifespan since it couldn't be used on anything else.
In conclusion, I cannot pass this on the merits of the EXE in its own right, on the merits of the SP level, or the merits of an EXE supporting the level without some of these issues being dealt with. But, given the obvious merits of what has been done, it does not deserve to be placed in the trash. For now, the topic will be left in submissions for a week or so, while you may choose to address either of the aforementioned issues. After that, if this has not yet been brought to a releasable state, this topic will be merged with the existing topic in editing, where the previous Dash's World topic is.
Good job getting this far, and I wish you the best of luck in fixing this up for a spot in Releases - Mods.
