I do like playing a twin shooter from time to time, these are some simple fun that I can just enjoy, and this game is no different. I think the game is a bit ambitious and unfortunately, quite a bunch can't be delivered on time (which we all understand, jams are always like this, so no need to feel bad about it), the game already has a solid core gameplay loop to work with. The gameplay currently although a bit simple, is still engaging enough to make an enjoyable experience. The graphics are pretty, and there is quite a nice ambient sound going on too. The game runs quite smoothly despite what you said on discord, so that's a job well done.
For some criticism, I think the thing that stood out the most for me is that there is a seemingly random delay between when you shoot and the gun actually fires. It makes the game feel extremely unresponsive. The delay is also randomised, and I can't find any hidden requirement (distance, movement, enemies, bullet on screens etc) for that. If it's an intended mechanic, it would be best if it were communicated clearly to avoid confusion. I would also say putting the two alternative attacks on Q and E makes using them awkward, especially when you are actively moving and avoiding the enemies. Last but not least, I think the enemies blend in too much with the grass/ground, making them very hard to notice before too late. I get it that it might be more real that way, but for an arcade-style game like this, it would be a bit better if they stood out a bit more.
Anyway, I'd say you did a pretty good job of making this game! Keep up the good work!
