Hello! Thanks for playing my game! I apologize for all the issues you encountered. >.<
The ESC key turning off full-screen wasn't an intended choice... It's something I never encountered, and I'm not entirely sure why this happens?? But I think it has something to do with me using Electron to host (instead of NW.js which is normally used for RPG Maker games). The debug version of the game doesn't appear to have this issue, and the fact I'm used to playing on maximized window mode is probably why it never came up while testing the release version. Not an excuse though, I definitely should've done better testing, but, well... only so much time with a game jam. Very tragic how one little oversight could be so catastrophic. XD (I cant update the game cause of game jam rules, but I'll throw a lil warning about it on the page 👌)
(Also apologies for the option menu, can't believe I missed that little "Touch UI" disabling soft-lock. Normally I'd remove the RM options screen entirely for game-jam games, but some people need for accessibility.)

As for the gameplay issues, I apologize, as the game definitely should've communicated this better: The "Materials" are actually supposed to be your main weapon. They are waaay more powerful and you can shoot them exactly where you want. Each material does different damage, and I was trying to go for a thing where you have to decide whether to use weaker, but more common materials, or stronger but rarer ones when it came to combat.
Since the Materials have limited ammunition (or can be used in trades), the skills were added as backup options (just in case you run out). However, the starting skills were purposely kind of useless to encourage you to use materials (The Telekinetic class doesn't even have an offensive skill to start with, so trust me, Randokinetic isn't as bad in comparison XD). Also, class only decides the starting skills. You can learn any skill in the game afterwards.

Anyway, I really enjoyed your gameplay! Thanks for trying to give it a shot even though you encountered so much BS right from the start. XD It's certainly opened my eyes to things I should look out for when testing in the future. Good luck on future streams!! ^^
