SuperTux pour Mac

Current release is 0.3.5a (May 2015) https://supertux.github.io

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".

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.

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.....

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.
