Literally could make it in my sleep. This game is so simple. You could probably code it after 1 hr of lessons. I don't even think it's real code I think they used a game maker like GameSalad or something.

Amazing! If this game had another name it would be called techno sperm simulator but that's not the point, this game is so good yet so simple I cannot believe how hard has this game trapped me.

Wow memories I played this when when I owned the Palm Pilot and look at what has become of it. Its still as addictive as ever before. Flappy Bird can't even touch this.

Best sound track ever I could listen to the song all day long! It like the best elevator music you've ever heard! This game is worth playing just for the music!

Like the ribon It's very easy!

Loved it I've had this game for 6 years and I still play it, timeless and flawless.

Dopest game ever Very adicting

Ah memories I remember when I used to play these when I was little :)

Amazing It is easy to use. It is fun to play

Fun New modes but slower I have always loved this game and had played it for years. However the additions of the 3d mode have also brought reductions in performance of the original 2D mode, even on my z1 compact which should be able to run it at full frame rate with ease. Not sure why this is but would really appreciate some bug squashing from the dev - and course will amend this rating!

Great! It's so simple, and games are generally very quick. The music is really soothing and nice. Unlocking the modes is very difficult, but feels rewarding. Don't worry, you can do it!

Performance issues? Used to be my goto game. Seems to have some performance issues now...

Sf cave It's too hard but it's got good 3d effects except it keeps on showing annoying ads of people going on dates and with those ads I can barely even play stupid ads!!!

I didnt like this game because it was hard but now it has sent me to competitions and it has become easy

Good game A bit glitchy traveling to the womb.

So simple yet so fun You control a blue snake through a cave. The graphics are as simple as can be yet the game itself is quite enjoyable

I understand the need, but the full screen ads turned me off from the game a lot..

It was okay kind of hard though

Wahoo! Finally I beat the game! Took me ages to get victory claimed!!!

LOVE IT It is awesome game need to play. It's addicting lalLLalalalalalalalala.

LOVE IT so much fun and a great lil time killer.

:D This looks awesome

best Is da best

Great game

Any aweome but hard game. This gamenis very fun. It passes time by and it has a little challenge to it.This game is probably my favorite game ever. If you don't know either to get this game or not I would highly recommend you get it.You won't regret it. Cause this game is awesome. I love it all my friends love it too.The good thing is that you can make different highscores and keep trying to beat them everytime you play.

Best game ever I have the current high score on "plain" mode (4890) ... I swear I get an adrenaline rush every time the cave walls get so tiny and I get a little bit further than last time. This game is incredible.... amazingly deep for only 1 button. Give it a shot and see how you can develop your skills, find concentration, and push yourself to your limits almost every single time you play. Hands down the best game for android, in fact I haven't been playing hardly any other games since I found this. Wonderful!!

The original and still the best! Way before Flappy Bird and it's million clones, long before smartphones, there was SF Cave. I had it on my Palm Pilot and enjoyed the Java app, but the Android version is a perfect upgrade that fills your screen and offers various ways to control it. Perfect for a quick distraction and with no invasive permissions or overly boated code. More Android apps should take a lesson from Sunflat!

I remember playing this game on the Web back in the early 2000s. It was a great time kill at work and the mobile app now allows me to kill time wherever I am. Nothing fancy, nothing complicated, just simple fun.

The original and best This is the ORIGINAL game of its type. Way before Jetpack Joyride and the copter game, this was out on Java and Palm. Fun and addicting, it is great to play while waiting for things.

Excellent simple yet fun and addicting game. if anyone things it's not challenging enough, play it upside down

Flappy Bird but Good This is pretty much the game Flappy Bird, except it is fun, and it came first . It's great to play for short time periods. However, it is somewhat lacking in content so it can quickly become boring.

Amazing copter-style game This is very much like Copter only better. Loving the background music! Add more music to papi games Amazing game, keep em coming P.S does SF in SFCave mean sunflat?

Love it It keeps me busy but there should be modes like endless or a mode were u can win and move to levels

Original ripoff This game is a bad ripoff of the original palm pilot game. Very badly made and is always trying to trick you into clicking on the ads.

Worst game ever This game don have any thrill and effort . Waste of time

Amazing game I remember playing this when was on the palm in greyscale. 100 times better than flappy birds.

Boring Don't recomend this to google.

Good game that fits into any 5 minute time slot Addicted, been playing it since it came out.

O for awesome So simply and addictive,shits all over angry birds.

Awesome It would kill time at recess addicting and I remember playing it back on my moms computer
