The game is really good man, I loved the power ups, my favourite new feature hahah, they make the runs a lot different from the others. It would be very cool to have even more different types of boomerangs.
The progression of difficult is really good too, after some time the enemies starts getting super fast, the risk of losing all my life in the start of a new wave is very big... on the otherside, the boss is always easy to kill when there's little to no enemies, triky to hit him (and thats the charm of the boss), but easy to escape.
The game is becoming awesome man, it gives a good roguelike vibe, and the particles in the game are very beautifull, especially the blue one that slows you (very dangerous enemy after some waves hahahah.
I think it could be cool to be able to regenerate my life a little, sometimes, but overall I really like the game, but the highscore is really high right now hahah, I wlll come back some day to give more tries
Congrats man
