Oh interesting, a randomly generated endless runner that's also a collectathon of sorts. As fun as this idea was though I feel like the way it's mashed up could be improved. The game doesn't enforce any fast pace, so you might as well meticulously try and collect the mask that's onscreen, so in that regard it feels like a collectathon but it loses that charm when you have to retry the level after one mistake (and since you can't go backwards). And dying happens pretty easily because sometimes you aren't even sure where you'll be landing and whether it's safe. A more zoomed-out camera may have helped that a lot. But yeah, this was a good idea to make into a little game, and it could definitely be improved by focusing on what pacing you want to go for (fast or slow). Good work!
