love this game, but i think it would be nice to have just a bit more gameplay later on. once you can get the time gain upgrade along with summoning, it becomes basically impossible to lose.
other ideas: more cannon types! i would love to see stuff like a laser (not bouncing) or something that shoots explosives, or perhaps a slow cannon with higher damage. some other stages would be cool too! im thinking like a square or octagon with a rotating beam in the center, or just a static obstacle if you feel like it.
additionally, it would be a bit nice to have an option to disable some effects for performance.
anyways, on to compliments!
i love the colors and ui, it looks really nice, is easy on the eyes, and generally intuitive to understand. the gameplay is simple enough to learn right away, but complex enough to keep me playing. the game is nice and balanced, albeit trivial near the end. i love how the tech tree works, its a lot more interesting than just normal upgrades. the magnetize upgrade is neat, i didnt expect it (i thought there would just be something like increased mouse range) but it worked out really well! also, the background looks really neat, and goes great with the general style of the game. theres small details too, like how not just the health of enemies increases but the fact that they slightly change shape too! overall, 10/10 game, love to play it.
