The concept of this game is cool as hell, and the execution is really solid! The whole idea of your movement changing according to an active wave is really awesome and I would love to see more of it :)
The art looks great! The different parts of the landscape complement each other really well and it all looks super tight- though maybe the electric balls can be a bit difficult to see.
The game is quite challenging, but I did manage to beat it- but the final level seemed to have a bunch of unnecessary spikes in it that felt as though they were punishing me for not having reached that part of the level before. I did notice there being some mechanics in the tutorial that didn't really get used in the final game, but that's just a game jam time restriction thing so no criticisms there :))
My main thought is that some parts of the game run in time with the player's wave, and others don't. I think the existence of the wave in the first place is a great idea, and obstacles are sometimes pulled off really well, but having some parts of the map (e.g: the two vertical lasers right next to each other on the last level, second electric ball on the last level) run on their own timings made those parts feel a bit unintuitive. I think that's an unfortunate tradeoff to have to make as I understand that having all the obstacles running on the player's waves would make the game less about platforming skill and more about just waiting for the right time- though maybe a bit more clarity on some parts would help? Like the two vertical lasers in lv2, for example, they're running on their own timings but it's really difficult to work out what those timings are- a graph or timer or something on top of them would solve that problem without locking them to the player's timing.
Holy essay, anyway I liked it a lot! Really good game, and would love to play some more of it if it continues to get worked on over time :)))
