BURLOW44  Won't launch on a PPC G4 running 10.5.1....the supertux icon shows up in the dock for a few seconds with the pulsing "active app" dot under it and then "unexpectedly quits".   
(Version 0.3.1)

DOUG S.  I've completed 19/20 of the levels, that being all of the main island and all of the second island, but I haven't completed the game. When I go to the bottom of the frozen make when I try to jump to that little island with two levels it instead puts me to the point where I can head to the right onto the bridge to the boat.

On the second island all the levels are beaten but there appears to be a single small island to the top right with one mushroom house I can't seem to get to.

What am I doing wrong? There is nothing about this on the site and it lists a 0.1 as the latest Mac version, which obviously isn't.

ANNMAIRE  This games is alot of fun.....i was actually looking for mario bros....and came across this game a couple of times i then finally decided to try it.....it is the same as mario the only difference is there is pinguin instead of mario.....it is really really run.....  
(Version 0.3)

JCTULL  This is a great game, open source or otherwise. For those of us from the side-scrolling era of game greats, like Super Mario Brothers, this is an excellent stand-in. I am glad to see that development progresses and that it is compiled as a universal binary. Runs great on my MBP C2D. Looking forward to Milestone 2.  
(Version 0.3)

G7  Maybe it is a good game, but I cannot tell it for sure, as it is impossible to download. For several days I am getting "Too many clients for /supertux/supertux-0.1.3-macosx-universal.dmg" message, from both mirrors. Maybe they should put it on a better server? Or create a torrent?

Or maybe it isn't the server's fault. Maybe the game is that popular? Every single Mac user is downloading it right now? And then, perhaps, he or she downloads it again for their friends, children and parents? Please, please stop downloading it for a moment, so that I could get it too ;))

KRYSTOF VASA  It's a great game, but an Universal Binary release would be even better!  
(Version 0.1.3)

RYU  Great game...soooo much fun....nice little game you can have in small (between lessons) or large (free periods) doses :P  
(Version 0.1.3)

ANONYMOUS  I love this already and I'm only on the second level!  
(Version 0.1.3)

ANONYMOUS  Entertained me for months during boring sixth form lunchtimes.  
(Version 0.1.3)

ANONYMOUS  This game is the best but when is the 2 one comin' out?  
(Version 0.1.2)

ABANDONED CHRONICLE  Great old school style game!  
(Version 0.1.2)

ANONYMOUS  very great  
(Version 0.1.2)

IAN LUECK  This is the best freeware Mac platforming game I've ever played. Seriously. Great Super Mario Bros.-style gameplay, customization with the user-created levels, and some extremely catchy, old school music. And some of the later levels are a PAIN. Exceptional framerates all around, too. Very nice work.  
(Version 0.1.2)

ANONYMOUS  great game, alot like the original mario bros  
(Version 0.1.2)

ANONYMOUS  how on earth do you get past the brown wall at the end of the first level? *very stumped* i've tried everything, and you just can't jump that high. what am i doing wrong?  
(Version 0.1.2)

GARPI  Wow what a rip off!

good work fella!  
(Version 0.1.2)

ANONYMOUS  Great game. Lots of levels, good action.

1 bug- turning on OpenGL inverts the mouse's vertical movement.

1 desired feature - to be able to go backwards in the level. Right now once you go forward, it won't let you go back.  
(Version 0.1.2)

PORTUGUESE FATHER  This is the favourite game of my 8 years old boy. He told me to get him another game similar to it. Anyone knows of it?  
(Version 0.1.1)

RORY  This is a great game! It reminds me a lot of Mario, but it has some different enemies and features. I can't wait for Milestone 2 to come out! There's just one bug–when I turn OpenGL on, the cursor moves up when I move the mouse down, but still goes right when I move the mouse right, so it flips over the x-axis.  
(Version 0.1.1)

JOHN JACOB  Great game---controls respond just like Mario used to on the 'Tendo systems of old, levels are challenging but not impossible, and graphics/music are both very good quality. I've already lost 7-8 hours of productive time to playing STux, and enjoyed every minute.  
(Version 0.1.1)

RENE SCHWAIGER  Quite cool game  
(Version 0.1.1)

ANONYMOUS  It Quits On me to but you can Still make levels.  
(Version 0.1.1)

ANONYMOUS  This one won't run on my Mac. It opens up, gets me through the main screen and the story screen and then unexpectedly quits when loading the game. :-(
