Thanks for Caveman! I know (and played) this game: this is a re-skinned Lemmings port due to copyright issues.
They used copyrighted assets indeed. For the Android game, I will deliver original contents only: I wrote original/not-copyrighted code and I created my own graphics, so I hope my game does not break any copyrights, even if my Brick tileset looks similar to Lemmings' Brick tileset.
i don't know why i never came to this website in the last 15 years hahah.. i just posted a new topic anyhow relating to caveman
we have an android version of the game now as well - it will soon be published for a closed beta.. in regards to legal issues - i've been versed up on this for years; Caveman HD never had any issues.. but, if your game looks too similar to the original game, you may run into issues. copyright law comes down to something as simple as this (this is how my lawyer explained it to me) "if someone with no knowledge of the game or computers in general saw the original and yours side by side.. but, couldn't tell the difference.. you can get sued for copyright infringement"... thats why Caveman looks the way it does.
PS: Caveman for Android has even been tested on Android 2.3.5 - so, 98% of android users should be able to play it!
