On the surface, this really doesn't seem like it should work as well as it does. An RPG where all you can do is watch your characters battle? No skills or magic? No equipment or treasure chests? Sounds boring AF.
But I found it was very cute and a lot of fun. Just the basic action of "number go up" is really satisfying, and it doesn't demand too much from the player, just a little bit of concentration. The bright pixely graphics are appealing to look at, and the characters are cute and fun. I encountered a weird bug/feature where the amount of time remaining would increase by 15 seconds or so (even above 5 minutes) when the character remembers a level, but it only seemed to happen after reaching level 13.
A winnar is me!
