I saw in the video, you asked if your ATK and DEF not going up was a bug, but that is not the case. What the level up system does is divide the level by 2 (except for level 1) and then rounding down. At level 4, your ATK and DEF should both be 2. However, watching your video, I noticed 2 bugs, those being the player battle effects showing the player, and also that the DEF started at zero. I will make a manual for the game, do not worry. Also, CRT increases every 5 levels. Thanks for playing my game!
