Hello,
Here is a new version of my little game 
Rock Dodger CE (Compact Edition) is an updated version of the original ‘Rock Dodger’ game from 2001 (by Paul Holt).
https://bitbucket.org/josephpaul0/rockdodger-ce
New features:
- Ported to SDL2, SDL2 Mixer and SDL2 Image
- Use 2D accelerated rendering
- Compact binary (less than 512 kb)
- All game resources are packed into one single executable
- Zero installation (unpack and run)
- Source code for the entire game is only 2000 lines in C.
- Works with i686, AMD64 and ARMv7 CPU
- Runs on low end machines : ASUS EeePC900, Asus EeePC701 and Raspberry Pi
- Requires only a 900Mhz Celeron processor for smooth gameplay
- Runs on all Linux distributions (from year 2007 up to now)
The universal binaries for Linux are there: https://bitbucket.org/josephpaul0/rockdodger-ce/downloads
I am looking for people who can help me debug slow hardware rendering on Raspberry Pi 2. Thanks !
