Holy guacamole! You guys are psychos!! XD 2 games at once, talk about sensory overload!! I enjoyed it though, but now need to lay down XD

Hope to see more like it, as the Fearless Four Dream Team


too hard for me xd
if there was a button for speeding up the tetris blocks a bit mayyybe but there was only one smash block down button and it was connected to the shoot and thats too much for me to handle
anyway nice idea


Whoops, there actually is a button to speed up the blocks (down arrow).  We just forgot to add it in the how-to-play haha...  Sorry about that.  Thank you so much for playing despite its difficulty!!


Having to play both tetris and a shooter game makes for some really good fun! I really love how the game was designed, and let's just say that I played the game very poorly xD

LOL, thank you so much for playing our game 1 Bit Monster.  It definitely is pretty difficult, but I'm glad you still enjoyed it =)


Beautiful artwork and UI design.  Ooh I love a good game of Tetris. Oh, I have to attack some ships at the same time. Seems tricky, but I think I can do th....THE DROP BUTTON IS THE FIRE BUTTON? :D You clever madmen.   I didn't last long, but I love the idea.

Haha, thank you so much for playing our game!  We put our 100% in this game for the Brackey's Game Jam, and we're grateful for your acknowledgment of our efforts =)


You guys nailed it with this one. Having to play both tetris and a shooter at the same time is perfect for this jam. I hope it does well. The game looks great, plays well and sounds good too.

Thank you Chafmere!  We're all hoping this game does really well in the jam.  So glad you enjoyed our work =)
