Hey mate,
Good little game, super solid, runs well, I had fun.
I did 3 runs, with a max score of about 750.
I think the Rage Mode could do with some changes. My experience with the Rage Mode was that for a split second I was glad to get a break from the monsters chasing me - BUT I was annoyed that they scattered to the far extents of the map. I was glad to get the break but it was annoying that it slowed down the flow state of the game.
An example of an alternative is that 'Rage Mode' could actually make all of the enemies flock to the center of the screen in a ball. In this way you must strategically see that rage mode is coming, and not get caught in the centre of it as they flock to the middle -> additionally this makes it a 'shooting fish in a barrel' situation where not only do you get a break but you get some free time to kill as many as possible, possibly even saving up your special attack to use.
The music was incredible (almost like an 8bit crunched Mick Gordon Doom vibe), I really enjoyed the sound design overall - but especially enjoyed the music.
I have a game in the Jam also - Tetromino Runner, if you found the feedback helpful come and drop us a line!
