It looks cool and I didn't give it a fair chance. it seemed to be overly complicated at the start of the game. I like tower defense games, but then when you are trying the first level it wants you to build an epic hero, I just lose interest in wanting to play. sure tell me how to play but then tell me how to do epics later. not be told to do fusions on the first level.

Thanks for giving it a try. Our game is a classic Random Defense title. The core fun and strategy come from constantly using Fusions to craft stronger heroes right from the beginning. Because Fusions are essential to the game's mechanics, we felt it was necessary to teach them immediately. We hope you understand our intention.

Can you put some explanation on how some upgrade works? Like, I don't understand how the fatal error upgrade works. It says it has a 50% chance of success but after a couple of times of fusing to a higher level summon, nothings happening. What does it do? Does it upgrade 2 tiers? It says 2 elite heroes, does merging the 4 summons to make an epic hero count in it? Are there any other methods not instructed? It's really confusing.

the tutorial is complicated for a new player u should split it into parts seperated when player level up. the idea of the game is basic and for that you added multiple features and that's good but it feels like those features are designed to fill the gap the doesn't add more value for the game the art design is good but could be better but the field design is terrible
