The textures are pretty good and the enemies' "AI" is quite refined, well for a Minetest game, at least.
I like the level design, but there doesn't seem to be anything after the "white box" level, you just go back to the place you started in.
Final ratimg: 3/10
I.A code is not my own.
The idea is random map change with few changes like old Atari 2600 games. But the time was not enough to make impressive modifications, only few changes in the levels.
