The game is fun and all but it's annoying when you are happily dodging lasers and the upgrade screen keeps popping up, especially when I have not enough points for the upgrades. It will be better if the upgrade screen appears whenever the player pause. There should also be a shortcut key for the "continue" button so there isn't a need to keep using the mouse when the upgrade screen appears.
I have a suggestion about the excess AP/gold: I hope that the game has an "AP/money exchange machine" or something like that, for every 10 AP that we exchanged, we can get 1 EXP, same goes for the amount of gold. Additionally, when there are too many enemies on the same battle, sometimes the crosshair and the "?" icon blocks each other, causing it to be difficult to click. So if we haven't scan the target before, it should be a crosshair with a "?" icon, whilst if the enemy has been scanned before, it should be a crosshair without the "?" icon, along with any weakness/resistance information. Lastly, since the EXP gained is too little compared to the amount of AP/gold earned, there should be a "training area", similar to the secret areas where we can find the treasures and strong enemies, where we can choose which monsters to fight, along with their levels. Still, this is the only game that kept me playing over and over again for weeks. 5/5.
The bestiary says that the Mammoth is not resistant to Doom, so I tried casting doomsday on it. Yay 5 turns left. After 5 turns, it only took 3600+ damage and thats it. My party died shortly after.. :(
