Interesting at first, but lots of problems
The game was interesting at first, but after playing it for a bit I noticed several problems.
1. Raising Battle Levels will make the monsters stronger, but the rewards for defeating harder monsters are questionable. (coins won are great to horrible. 190~2000 at the final level)
2. Getting new weapons doesn't seem to do anything. No graphics change, no noticeable damage increase)
3. Damage dealt to you are totally random, you will get 1-shotted if you get an unlucky crit.
4. Why can't WE do CRITS?
5. Normal attack and Magical attacks are obsolete once we get skills. What's the point of them existing if we never use them? If I run out of energy at the boss I'm already dead anyway.
6. The final boss is OVERPOWERED. If he crits you it's a 1-shot.
Getting the levels and stats to defeat him is a terrible grind. Grinding make the game extra boring. Add the random coins won and it's extra tedious.
7. Only 5 types of monsters, and most of them are from final fantasy and breath of fire. Get more variety.
The game needs some serious balancing issues. If you want to get into more serious game creation, try resolving them in the next game.
