<Me when I play this game.
You play as the one eventual blob that will avenge all the previous blobs that one spiky boi and his lava wall friends has rekt by surviving longer than the last. And lowkey if you're as bad as I am you probably will be avenging a lot of blobs.
The controls feels good and fair. It has the right amount of response time for the blob to follow your mouse whenever you make a move. The blob can only move so fast so you'll have to anticipate your own actions. I think the delay slightly adds to the difficulty of the game.
Animations and art style were really well done. It's simple and fluid. Nothing too crazy and strategically speaking given the time frame, it was a really smart move. I think the final presentation really paid off. Sound design was good.
For gameplay, I haven't gone pass higher than 221 so I cannot speak for the game's level variation pass that score, but from what I've seen so far the speed at which the game ramps up the difficulty is good. I didn't think it took too long to get to my previous score, but I have suffered to 100 in flappy bird so I might be bias. The quick tutorial in the beginning was also a nice touch.
I know I really didn't say much if any negatives at all, but from my pov with the time allotted, this is pretty impressive :) I think like some others have said, if given more time this idea can be expanded upon even more, especially on mobile.
Thanks for giving me the opportunity to try it!
