I added some polish to the game over the past 2 days.

• Some added SFX (not great, but they fill in some blanks)
• Painted environment tiles
• Parallax background
• FINAL BOSS - relatively simple giant scaled melee enemy that makes the game even harder hooray!
• the Bomb has some of its own (very slow) momentum, meaning it's possible to complete the game solo (though it's a slog)
• You can ride on top of the bomb!
• Ranged enemies aim from their weapon origin (beware!)
• RagTagRadical Logo (LOOK AT MY HORRIBLE FACE)
• Dashing hurts enemies
• More heads
• Fixed freeze bug with object collision
• Fixed detonation not occurring when on player 2+

I learned how to do tiles in Gamemaker (finally after 3 years), and found it to be a lot of fun.

I created a pretty rough image, and then I broke it down in gamemaker into 32x32 tiles, finding different shapes and patterns out of repetitive tiles.  It was actually really satisfying painting the landscape from this single sheet.
