veeeeeeeeeery long game for a jam. i am impressed and horrified all the same. i have already sent my thoughts to one of the developers over discord, but will rewrite them here:
1. visuals are excellent, best of the jam. most every action/interaction had a sound effect attached, and this gave the game a professional sense to it. the game is polished to the nines, simply put. however, i feel that the music was, at points, an obstacle to my enjoyment of the game, for (in the one hour it took me to play the game) there was very little variation. i thought it was just one track, but the developer told me that there are variations upon reaching the ending and entering the pyramids.
2. the movement system does not suit the level design. i find that momentum-based movement systems work best for platformers with big levels that allow the player to acquire a lot of speed and don't require a lot of speed, wherrrrreas this game is designed more like a precision platformer. but it is very hard to achieve precision with the controls. it is, of course, manageable (...i beat the game), but does not result in any joy.
3. the central concept is neat. i have seen it before (most notably in this 4D puzzle game that I can't remember the name of), but it is still neat. however, it does not feel very well explored here. a few puzzles use these mechanics, but not too extensively.
4. the length was absuuuuurd, especially because of #3. i made a joke with my co-developer on THE RAPTURE... that one could easily (easily!) make a one-hour game within a game jam if they were to make a platformer...well, you have made a one hour platformer in only a few days. my problem with the length is mainly that there isn't much surprise. the third timeline added does shake things up a bit, but not thaaaat much and not for long.
5. still, there is an enigmatic sense to the design that i do appreciate. the abstract visuals and minimal explanations culminate (early on, especially) in a novel spatial-narrative sense, which was appreciated, though this attenuated as the mechanics and symbols became understood.
