got a high score of 183, which at the time of writing is the highest.
an engaging game! i think the highlight to me was your use of visual assets and the animations. i noticed through playing that the platforms have predetermined arrangements rather than being wholly procedural, which is an effective anti-softlock method. overall your execution of your idea was good.
however, i do think the game had room for improvement in a few areas. i think there is very little game juice/feel in particular; few sound effects were used (though the coin pickup sound is nice), and i didn't feel like the act of jumping and platforming was very engaging in and of itself, which prevented the game from being truly addictive to me. i think that, as the game's main focus, that could have used more emphasis. i note that this game was submitted nearly four days before the deadline - i think given the excess time you had, there was room for more polish in general.
i also think the difficulty could have been dynamic, as the lava appears to travel at the same speed throughout the entire game; i quickly moved upwards so that the lava was offscreen, and never saw it again until i decided to stop - in which i backtracked, then fell as the previous platforms had despawned, and i plummeted for a full two minutes before meeting the lava x) which gave me the impression i could've kept that run going for much longer.
regardless, as before the fundamentals of your idea are clear and quite well executed, and i'm sure this could become very engaging with a little more polish and freshness. well done!
