That... ball... thing... from the smash hit* Rebound is back in a new kinda-sorta Metroidvania style adventure with slightly wonky collision detection! Rebound through 5 different areas in your quest to... uhhh... what was the story I came up with again? No matter. YOU'RE A BALL. DO THE THING WHERE YOU BEAT THE GAME.

*Probably not

water segment in Impossible-mission-base actually is impossible.

A. It requires precision timing, but direction timing and special action timing are too out of whack compared to one another. (it takes low bounce too long to activate)

B. too many false (as opposed to just wonky) hits in the area.

C. might be solved with an extra beacon

It definitely is doable, but I'll admit I may have gone a bit overboard with the spikes. I'll look into making the section a bit easier.


Tic-80 is now able to have 16-bit graphics?

Nope, just clever use of the 16 available colors ;)

Ah! Ok, it's like in the graphics of the Sega Gamegear and Master System, that by the colors it looks like 16-bits, but they aren't, is a trick to make the game look better graphically.
