I completed a game in BABY mode, I think some score or something like that was being displayed but pressing a button got me back to the main menu.
I think 20x20 is already quite big with thin walls and 1 room = 1 tile. It didn't help that I had to explore the entire dungeon before finding the exit.
The game feels specially good. It sounds cool and looks great, the visual feedback on the monsters for smashing them is good, the atmosphere is great and I love the instant movement and combat that you can control as fast as you want although feedback is not exactly instant. Controls really feel great.
In theory I love the combo system. However in practice combat did not work that great for me because trying to apply the cool combos I discovered by chance (X10 DMG, + 1000 HP) was very risky and would have eventually got me dead while on the other hand mashing the buttons would let me unharmed so I did just that and I can't say it was completely satisfying. I ended not enjoying the combat as much as I wanted to.
Overall this is a cool entry anyway, thanks for sharing.
