Mech Chip

Metroidvania where each suit has 1 ability and you have to switch suits on the fly to progress. Decent map. OK music. Haven't fought any bosses yet. Not really any story, and 1-bit graphics, but is that any different from Metroid 2?

It's short and neat, but also a bit clunky

It's okay. It certainly doesn't deserve a downvote and it is definitely priced fairly. It's got a nice aesthetic and a solid concept, but the mechs swing heavily between braindead and insanely situational. At the start, there's a tiny bit of incremental progress as you get more movement and combat capabilities, but the latter half of the mechs don't meaningfully change the gameplay beyond "now I can open a different type of door". There were a couple tiny bits of telegraphing I liked - a certain enemy that matches the shape of a certain mech is able to walk thru spikes that were normally harmful, and a destructible platform far out of reach tricks you into breaking something you might not realize you can break. I think the dev has talent and I'm happy to support them, this is just a genre that has set a very high standard.
