Yeah, I kinda noticed late in development that it was starting to get a bit repetitive. The game was actually intended to be longer, but the first few iterations weren't different enough to me and I couldn't come up with enough iterations that I felt would feel different enough, so I decided to just, make it a bit shorter than I originally planned and hoped that'd help make up for the game's lack of variety, by hoping it wouldn't overstay its welcome too much.
So, suffice to say, it's a problem I'm aware of and isn't something that likely would've remained in a game where I had more dev time to smooth out the issues. Sometimes when making a GameJam game one just runs out of ideas and doesn't have time to come up with more though, heh... ah well! Kinda knew it'd probably keep the game from being as good as it could've been, even if I'm still pretty happy with what I was able to make given how rusty I am with GameJams at the moment.
That being said, I'm planning to participate in Metroidvania Month in the future, maybe next time I'll try something less experimental- who am I kidding I can't help but try to experiment at least a little when it comes to GameJams lol. Mind you I probably won't try for an idea as odd as this one, but I guess we'll see what inspiration strikes me when I see the theme of the next one in a few months.
