It's a shame you'll be unable to attend, 'cause this is one of the higher tier games in the whole lot so far for me, even though I'm stuck at Level 5, which should perhaps be pushed a bit later if you ever add more levels, whether you expand it to 50 or 100 or whatever, but hey, it's part of the challenge, as I always say whenever I get to a particularly challenging point in a game. Maybe if the CRT shader was animated, the UI was more exciting and the music and SFX didn't default to 0 while still letting the music play and both defaulted to, say, in the middle, I could've even placed this one in 3rd for the Public's Choice award, yet you wouldn't be able to claim your prize, even if it's just bragging rights.
I don't really mind all that much personally, but I would've tried to avoid the potential ire of the big companies by replacing the copyrighted characters with original alternatives, 'cause I'm not sure they'd be willing to work with you on this one. Their branding would probably have to be more prominent than you'd be willing to do, and even if you complied with whatever terms they come up with you probably wouldn't be able to afford their licensing.
If you decide to develop this game further, I'd recommend adding a level editor and a system to upload your own levels, 'cause this game is prime for that!
