Why everything is in pixels but the menus... ?
It's short fun, especially since there is no real way to know how much damage you're about to make, or how much recovering you're doing. You can still end up with an accurate win rate but the battle will simply takes some time. It needs a little bit more to have a fun gameplay, maybe a shop or a way to unlock character. Or some points reward other than cash to buy 1 point upgrade.
Otherwise it's still a good job.
