Sandbox Engine DS-DSi is a 3D FPS style DSi hybrid (for DSi only but also playable on DS) game which started back in 2010 on the DS but when the DSi sudokuhax was discovered its being made with DSi mode in mind.

Changes:

minor changes…
fixed some lighting.
changed title screen.
changed some controls.
this version has some small fixes from the last version. & some things i forgot.
(note: lighting depends on what emulator your useing. but the correct lighting should work useing flashcards & sudokuhax.)
Edit sorry guys had to take it down for a sec, its back now tho, accidently named it v005, fixed it
