Thanks for playing, and glad to hear you 100% it. I unfortunately didn't have enough time to implement a secondary ending, best I managed was just showing your total on the "end" screen.
Re trolly platforming. Hah definitely not intended, but I agree there are some spots. Since I didn't have enemies spikes were pretty much the only thing I had to introduce any challenge some segments are definitely a bit punishing. Thats why I had very non punishing respawn like you said. (no health or actual death, fast respawn).
And yep there is a bit of AI art. The intro/outro graphics were pretty necessary to get the vibe I wanted for the game and not something I was able to create or modify existing content for myself. I did modify the generated assets a good deal (probably made them worse in many ways because I am bad at art) but I wanted them to be in the same limited color palette and feel kind of gritty.
