Gentlemen, there is a moment in every jam (ok, almost every jam), where you play a random game, and you know, you've struck gold!
Let's start with the graphics- using pentagons, one circle, but also some smart particle effects, colors and animations you've created something really stylish. Hell, even the choice of color palette works here! And the negative colors at the end? Bravo!
The music and sfx? Everybody loves Megalovania, and I'm not gonna pretend I don't. Brillo!
Now lets talk about the gameplay. Five bosses? With different mechanics? With a secret boss fight at the end? Awesome! Oh- one more thing! Making the game easier after you fail a couple of times? Brilliant! After all- it's a jam game, not a soulslike!
Are there things that I didn't like? Well... no. I guess one time when the pentagon talked while positioned over the border pentagon the letters were "above" the screen and I didn't see them.
Brilliant work guys!
