Big fan of PICO 8 console. I know its kinda hard to develop games in pico 8 but I would say that just a little more environment and ambient stuff will make it look cool! After all sprites are well made. Good job!

nice little game, pixel art is cool. the background is a bit boring but it's ok.
music is fancy but gets a bit annoying fast.
games starts very slowly. it could develop to have checkpoints and more moving obstacles mechanics for exemple. you can also get yourself in a corner so the game plays itself without you interacting.
coins and crosses overlapping is not ideal.

Very interesting game, at first it was boring, but when I didn't collect the gold nuggets this time to make it into an obstacle I found out the interesting part of the game.

Very cool and enjoyable game. Love the ease of use and style.
Music can be turned off, which is also a big plus when you play for a long time!

The game starts off pretty slow but when you stop being able to keep up with the gold it gets more fun. Without any time or animation between the spawns it can be a bit disorienting though.

Cool art and sound (although the music started to get to me after a few minutes). Really liked the concept especially once I "got it" (after I missed my first piece of gold). There was patch of time where I was building up "red zones" I couldn't move into and I thought that concept was great. Unfortunately a bit after this I ended up in a loop of running around a small circle of safety which I think would have gone in indefinitely.. it'd be cool if there was some sort of creeping threat or reason to take more risks.

At first I thought it's going to be repetitive collectathon but after couple seconds, I realized where the threat it. Pretty good, I might use the idea for my next game ;).
About the game itself, it's kinda repetitive and despite the red X's, it's possible to just collect golds in small area ignoring the rest to get optimum result while surviving long time.

Very interesting and not so boring once there are a lot coins on the screen. It's very simple but the mechanics really fits the theme. For a first try with Pico8 it's a really good start! Maybe you could make the music change a bit? It could depends on the number of coins or cross in the screen...
Keep up!

Thanks for all the feedback, it will help me for future projects.
