Thematically speaking it is quite refreshing to see a game made using the engine that avoids the all too common survival-sandbox game genre.
Despite being unfinished, I found it to be enjoyable and at times engaging. For the most part, the simulated opponents behave pretty convincingly like actual racing contestants (though I have seen a few glaringly obvious exceptions).
The camera jitter is off-putting and feels like typical engine stuttering, but it is inherent to Minetest’s camera manipulation and cannot be avoided.
The soundtracks are good, and seem appropriate for the environments where they are used.
The menus are nice, I quite like the Invector font and rotating character selection images; though I felt they lacked a more personalized background image that could have tied the other elements together well.
The item and weapon indicator textures are relatively easy to distinguish from one another (perhaps improving the accessibility of the game) in shape and colour. Most don’t seem to conflict too much with other visual elements.
The speed boost indicator and weapon selection crystal felt somewhat intuitive and were easy to learn. Some of the weapon indicators were easier to learn than others (rocket, shield, sand, boost variants). This will probably vary for users with differential exposure to similarly designed games, but I think the developer worked well within the creative limitations they had.
It is impressive that there even is a track editor on top of the main game and I would love to see what others make with it. The track editor could use some more builtin tools and documentation, though.
I surmise that (like the other contest submissions) most of the deficiencies would have not existed had the developer been given more time. I am fairly confident that this game will be improved upon further, and I look forward to seeing where it goes from here.
A very promising project produced by a quality MT dev.
