I should replay the earlier version to see how much has changed, but your initial submission was pretty similar, but now it's more polished!
I did run into what might be a bug though... Or at least something unfortunate.
After beating the game with a character, I was happy to unlock time attack. Plus a new character! And so I played through that once...
However, after playing through it again, I wanted to switch to saves, but saw no way to switch back to normal mode, So I chose new game...
But new game is really a NEW game... No time attack and no extra character. So when I saved I had to beat it again to unlock it.
While the mod is short enough, I didn't want to restart. (Already played multiple times.)
I stick by what I said in my last post about Task Force, but to add:
Task Force has the best gameplay imo. Cave Story's engine is usually best with combat and the various weapons, enemies and bosses make for a fun little romp.
Story is very basic, but on point with the sci-fi theme. Neat character select too.
I have some mixed feelings with some of the graphics, and some parts of the music, yet it all mixes quite well.
Nice adding the pear, and a cool feature, but unless I missed some secret area; was relatively useless besides feeling like Sonic for a moment lol.
(I guess for speed running?)
Overall, nice submission. Reminded me of old DOS games, which I enjoyed. (Nice with the save point info sign! x)
My only wish was that you added even more with all that additional time. I'm greedy. Morrrre levellls, Addditional storrrry background, etc
