This is a nicely done 2P game! Really fun having a lot of curses on yourself while still trying to control your tank and evading your enemy's shots. The art and the music are good too. The only thing I wish was handled better was motivating the players to go and take more "Ingredients" (or curses) not just doing for the sake of testing the game. Still I can only congratulate you for your job on your game, great job and keep them coming!
Good game, had lots of fun playing it. The effects of the curses are really cool and different. I wish there was a reason for me to pick up the curses, maybe the game could have points and the curses would work as a multiplier, I don't really know. Also, maybe add an indicator for the amount of kills? (Maybe there is one and I didn't see it)
Some of the curses were too much of a negative modifier to be worth getting, I would be careful about stuff e.g. the control swap. Decent entry though, reminds me of Return Fire.
Cute! Of all things, the thing that came to mind when I was playing it were the powerups that messed up your opponent's controls in Yoshi's Cookie, so bonus points for bringing back good memories :)
And just like that game, if I were going to play this game more, I'd probably be training myself to play better with the curses active :D
Balance felt right and you came up with a good variety of curses.
I'm afraid that I don't have a second player around to play with, but I believe I got the gist of the game from testing it out alone.
The core concept is a good take on the theme, and makes a lot of sense as a multiplayer game. Interestingly, there aren't a whole lot of games that involve competition for negative items, despite that it's a pretty effective mechanic.
The music works well, although I could see it becoming repetitive at some point.
The graphical effects are all very effective. However, they legitimately made my head hurt a little -- and if that is a common symptom, perhaps the effects should be toned down a bit.
I also wonder if perhaps the game would be benefited by a mechanic that let you drop your curses? Or maybe one that let you shoot them at the other player? Just ideas, as, again, I didn't have a second player to play with.
Really, though, the only thing that I think would be particularly beneficial would be some sort of single-player mode or online mode, as those are both more convenient than local two-player splitscreen. Of course, they are also both significantly harder to implement.
Just a tip: Add some screenshots!
