The gameplay was great, but I really have to shout out the UI design. It's one of the things I really struggle with and here it looks so clean, cohesive and comprehensive. Combined with the audio and visual effects being on point, it makes this the game with the best presentation I have played this Jam so far.
I feel that the probes regenerating over time and health refilling at the start of each level really goes against the limitation though. It also makes the probe capacity kind of pointless, if I ever ran out, I could just chill at one spot for a while, but since there are so many probe upgrades, I was usually at full capacity anyways. You could IMHO reduce the max capacity to 25, remove the regeneration and it would still be fine.
But that is more or less the only critique I have, really well done.
