''A virtual pet game with boxing

This is a game where you make a virtual pet (tamagotchi) and look after it by feeding it and making it sleep. Also you can train it so that it becomes stronger and faster and make it fight other tamagotchis in a boxing match.

This game tries to be child friendly and is challenging for both children as well as adults.

I made this game for my university project. I made it in only 2 weeks so it is not very polished.''
