Well a friend recommended this game to me, and I definitely don't regret playing at all. This was a really fun... I guess platformer "roguelike"? With the weapons and stuff. The overall theme was throughout basically the entirety of the game which was crazy. The amount of variety in enemies and the cool ideas behind the weapons were awesome. Basically all the weapons made me want to use them, even if I did end up spamming the infinite ray to double damage the boss...
If I was to comment on a few things that felt a little weird to me. It would be the system where you are stuck to a platform moving up etc. because a lot of times it messed with me and getting off of it was a little involved. Not too difficult, but it did feel a little sticky sometimes. Especially since you aren't able to use the S button on the walls. Plus the controls changing, though that only really surprised me once.
Other than that tho, 7 is freakin hard. It took me sooo many times to just survive without falling off the platforms while avoiding his attacks. But he was definitely fun to fight. Overall all the bosses were fun. Heck, most of the enemies were unique, made sense and had their own unique attack patterns, health bars (that almost made sense) etc.
You really went in on the fact that this was a math based game. The setting with the platforms listing off their location, the enemies with their designs, attacks, health bars and specific animations. Not to mention the massive variety of numbers used (how'd you do that anyway?).
So far my one of my favorite games in the jam for sure.
also name suggestion for a #2 from a friend, "7's gone mad: to the power of 2" (I'd play it)
