did I complete the game?: It's not that kind of game. I did score 15,000 points though which I think is pretty good.
what i liked: Out of all the games I've played so far this feels and looks like one of the best. The different powers are interesting. Everything looks and feels very smooth and polished. And it's just fun! the sfx and the music are nice. I like the little note at the menu about "getting this over with". It all felt unique, finished, and very fun. This honestly does not feel like a jam game. It just feels like a regular and good game.
what I would suggest: The different powers are interesting as I said, I would do more with them. Maybe every thousand points or so it switches to a different shooting style. Or maybe you have to unlock them and each is slightly more powerful? I'm not sure. Other than that there really isn't much more to suggest. Maybe just do more with the game overall because it's got a very fun and good core gameplay loop. So maybe it just needs even more gameplay. Last idea: some breaks in between the waves would be good or else it could create a very intense game experience without many breathers for players who are playing for a long time. Every couple minutes or so a few seconds to recoop would be good.
overall: One of the best games here. This should be top 10 easily. Great job. I think with jams people shoot for the stars which is great and all but not if your game isn't fun. This is just fun at the end of the day. I want to play it again!
