This is gonna sound like a crazy comparison, so bear with me here.
Y'know how google sometimes does games for the google doodles? usually around the Olympics or Halloween if you click on the google logo it'll take you to a fun little game you can only play that day. I feel like this is the kinda thing google would make centered around the "no internet" dinosaur. The visuals are surprisingly polished, and there's more depth than meets the eye. I dabble in touhou, so the graze mechanic is super welcome. Its a really fun way to implement risk and reward. Do you play it safe and focus on getting through the obstacles? or do you go for style points and try to hit graze for some insane mult? If you're anything like me, you'll go to graze and bonk your head on the underside of a dinosaur, ending your run. Oops! One thing I would have liked would be some sort of visual indicator of what the graze range/hitbox was, since I found myself constantly thinking "I'll totally slide under here" and ending my run because I couldn't tell exactly where the hitbox began and ended. Touhou, for example, has a "focus" mode where you can see the exact hitbox of any given character, which makes grazing a lot easier since you can see exactly what counts as "just barely hitting you". The perspective of the game makes it a little more easier said than done, but Id bet there's a solution somewhere. But yeah! Lots of cool stuff here. Online leaderboards are a super nice touch, and I think with just a little tightening up, you got something really special here!
